The first ones were released summer 2006. And they're just as good. I had one (E6600 2.4GHz). They can deal with 1080p just fine. Even better if you have a Core 2 with four cores, then you can do other stuff too without affecting video performance. The only reason I upgraded to an i5 is for video games (in Windows). For everything else, the Core 2 from 2006 was very comfortable to work with.

[gentoo-user] Why is gnome-2.32.1-r1 requiring the gnome-3 nautilus and evince?
I run gnome3 on a test laptop, but want to wait until intersession to install it on my real laptop. I will probably like gnome3, but had a bad experience a few months ago when gnome-shell repeatedly crashed so want to wait for a quiet time to do the upgrade. Anyway, weeks ago I installed the package.mask list and all was well until this morning. Here is the beginning of the output from emerge --tree --verbose [the full output is below] Calculating dependencies... done!

The end of the emerge output says that gnome-2.32.1-r1 requires evince-3.2.1-r1[nautilus]. I looked at the gnome ebuild and don't see why it wants nautilus from gnome-3 or evince from gnome-3.

If you use dd to copy an encrypted disk, the result will be missing something like 90% of the data. I have no interest in tearing apart the DVD in any way. It was more about the idea of a fire causing the loss of maybe $15K-$20K investment over the years. I can rip all the CDs, keep the ripped version here to watch on the computer, and store the DVDs elsewhere, but that elimiates (generally) being able to watch special features which my wife and kid enjoy. No it doesn't. You can use dvdbackup (or k9copy or ...) to copy the DVDs to the computer and when you play them back you get all the menus and special features and whatnot. If you want you can create ISO images and burn them to dual-layer-DVDs, but you don't need to do that to play them with all the features. So for my continued education, if I take an encrypted movie I can use program XYZ (Linux or Windows-based...) to create an iso image, but that iso image won't, even if it does include all the special features, ever be a bit-for-bit copy of the original. It's now unencrypted and created anew. Exactly. I used to use k9copy, but I got tired of fighting with Qt dependancies and switched to dvdbackup. Sometimes I create ISOs and burn them to DVDs, but usually I just create directory trees and watch them via a SageTv set-top-box that mounts the directory via NFS. It's a completely different way to represent the original data. Yep. I'm not aware of any Linux software that can create an encrypted DVD -- but I've never had a desire to do that, so my lack of knowlege of such a thing shouldn't be used as an indication of non-existence of such a thing. :) That said, if it's a _complete_ representation of the original then the special features are there, and if written to a DVD _might_ work in my DVD player, They've always worked in the DVD players I've tried them in, including subtitles, special features, multiple audio tracks, etc. The various backup programs usually have options to pare down what's copied so that you can do things like copy only the main title with one audio track (with or without menus, subtitles, etc). Some of the backup programs will also re-encode the video to make the end result fit within a specified size -- for example you can generate a 4.7G ISO image from a 9GB original. assuming the DVD player isn't specifically looking for something that was on the original disc such as specifically encrypted blocks of data, etc. Am I getting closer? Indeed you are. -- Grant Edwards grant.b.edwardsYow! How's it going in at those MODULAR LOVE UNITS?? gmail.com

[gentoo-user] -march=native is *EXTREMELY* conservative
Here's the setup of my secondary machine.. It's a Dell Inspiron Desktop 530, with 2 gigs of ram, assembled and shipped August 2007. It has an Intel Core2 (*NOT* a Core2 Duo) cpu. From /proc/cpuinfo... vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Genuine Intel(R) CPU2140 @ 1.60GHz stepping: 2 cpu MHz : 1595.660 cache size : 1024 KB Here are the cpu flags... waltdnes@d530 ~ $ grep flags /proc/cpuinfo flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc arch_perfmon pebs bts aperfmperf pni dtes64 monitor ds_cpl est tm2 ssse3 cx16 xtpr pdcm lahf_lm dts Then I ran gcc -march=native -Q --help=target and got a major shock. It's a long output listing of what -march=native thinks about my cpu. Here are some relevant items... -march= core2 -mmmx [disabled] -msse [disabled] -msse2[disabled] -msse3[disabled] -mssse3 [disabled] It properly identified the cpu as core2. But mmx, sse, sse2, sse3 (aka pni), and ssse3 are disabled!!! The reason I dug into this was that I was trying to 1920x1080i streaming video from my HDHomerun TV tuner box. I originally used CFLAGS=-O2 -march=native -fomit-frame-pointer -pipe when setting up the system. It could not handle 1920x1080i streaming TV video. After findinding out about -native, I changed CFLAGS to... CFLAGS=-O2 -march=native -mmmx -msse -msse2 -msse3 -mssse3 -mfpmath=sse -fomit-frame-pointer -pipe ...and emerged system and world and rebuilt the kernel. Now the onboard Intel GPU handles 1920x1080i flawlessly. As a matter of fact, it handles 1080p flawlessly. -- Walter Dnes waltd...@waltdnes.org

Right now, powered on with no load just to judge it for this conversation, I can hear it if my ear is a foot away from it, but not 2 or 3 feet away, not against the normal background noise in my apartment (clock ticking in the kitchen and so on).

But mmx, sse, sse2, sse3 (aka pni), and ssse3 are disabled!!! I think you may be misinterpreting that output. It's not telling you that MMX etc. are disabled, it's telling you that the /commandline options/ are disabled. Why? From the GCC docs: core2: Intel Core2 CPU with 64-bit extensions, MMX, SSE, SSE2, SSE3 and SSSE3 instruction set support. That means those features are implied by -march=core2, adding those commandline switches would be redundant.

I think, typically, when a DVD with copy-protection is manufactured, it is sent on DLT tape or a special DVD for Authoring disc which contains the unencrypted movie but also an extra area with encryption data needed by the disc manufacturer who can press the real, encrypted DVDs. In other words you can't burn your own CSS-encrypted DVD at home. :)

These players allow you to treat .iso files on the network just as if they were actual DVDs and give you full access to the menus and extra features. At least mplayer, vlc and xine will also happily play a directory, be it a mounted DVD, a mounted image or just a rip as made by dvdbackup and others (e.g. lxdvdrip). The SageTv set-top box will happily play a DVD directory also (in addition to playing TV shows recorded by the SageTv DVR server software). Practically all players will do this, I think, but I much prefer having the DVD as a single file, to move and copy and store. A directory containing a a VIDEO_TS and a load of files just seems a lot more fragile to me. Were you to accidentally delete one of the VOB files, there would be no way to tell the difference from looking at the outside of the video's folder. True, but that's never happened. ISO images work fine, but the extra layer of indirection is an inefficiency that irritates the engineer in me. ? I absolutely dread going to back to MythTv with a big, hot, noisy PC sitting next to my TV? I bought an eMachines 1401 recently - it's not as perfectly silent as the PlayOn (which is fanless), but it's *very* close. It's an AMD atom-equivalent, dual-core, mini desktop PC, about 7 on a side and maybe 1 thick. Right now, powered on with no load just to judge it for this conversation, I can hear it if my ear is a foot away from it, but not 2 or 3 feet away, not against the normal background noise in my apartment (clock ticking in the kitchen and so on). Right now its hard-drive is louder than its fan (which is shifting so little air that I can barely feel it, even putting my hand an inch from the grille). I think that if you load it up with an emerge then the fan will ramp up a bit, but I doubt if you'd notice it when watching a movie. There are some platforms that are getting pretty decent, but they still cost 5X as much as a set-top-box box, draw 10X as much power, and are about 4X larger. They're probably approaching tolerable, but compared to something like a Roku or SageTv box, they're still an embarassment. I used a Mac Mini for a while as a MythTv frontend, and it was quiet enough that it wasn't noticable unless the room was dead silent. It would have been OK if I had been able to get DVI output working. -- Grant
