NOONE, even the uber geeko genius, has ever heard of making a backup.

Yes, but...

Keep in mind that these new $9 per month movie services may have 
done just this very thing, since no way will the consumer pay for a 
movie that is of the general quality that is downloaded from the web 
and shown using Quicktime or Real.


MPEG-2 is often decoded in hardware.  That hardware is either a 
special chip in the DVD drive or in your video card's GPU.  Some 
newer video cards have the necessaries for decoding h.264 in hardware.


Iffa your Mac no gots the required hardware, then QuickTime (or VLC 
etc) has to do ***all*** the decoding your main CPU.


Now... That $9 service.  They PAY thru the nose for their network 
bandwidth, so they have NO interest in streaming lower-compression 
data to you.  They want to send you as little as possible, hence the 
use of advanced codecs such as h.264.


So to view compressed stream smoothly, you need two things:
1) A fast CPU or some sort of hardware decoder
and
2) A fast/smooth network connection.

If either of the above isn't up to par, then will get pauses, stutters, etc.

Your 450-MHz G4 is simply not fast enough, I think.

Never mind. Found it:
http://www.gigadesigns.com/jumpers.html

But since this site is no longer available, the web archive is the saviour of 
the day… http://web.archive.org/


I still wonder, what the backside small jumpers are for. Maybe it's not the 
voltage, maybe it's the cache speed i.e. multiplier for the L3 cache?

Giga Designs G-Celerator G4/1.0 AGP jumper settings – please help

[Mac User #330250]

Hi!

I've acquired a Giga Designs G-Celerator G4/1.0 AGP (5-9310U) CPU unit that 
was running in a Power Mac G4 AGP (originally 350 MHz) *overclocked* at 1.2 
GHz. It was running flawlessly at this speed, so I guess this greater than 20% 
overclocking is no problem for this very G4 CPU.

The G-Celerator G4 GC5-933-S2 is actually a 933 MHz MPC7455 that was 
overclocked by Giga Designs to 1.0 GHz which makes it by design 7.18% 
overclocked.

http://www.everymac.com/upgrade_cards/gigadesigns/g_celerator/g_celerator_g4_1.0_agp.html

I guess the GC5-1000-S2 is very similar:
http://www.macworld.com/reviews/product/406426/review/giga_designs_v_gcelerator_gc51000s2.html


My only problem is now that I cannot find any documents on how to set the 
jumpers to make it run at any other speed – or for a 133 MHz system bus for 
that matter.

I know that right now it is set to a multiplicator of 12x (100 MHz system bus 
×12 = 1.2 GHz CPU), but this is no help at all. I also don't what to 
experiment with the jumper settings.

These are right now:
J1 through J5: closed – closed – open – closed – closed
J7 through J10: closed – open – closed – closed

I did find a PDF file for the Cube version, but it isn't at all adoptable:
http://cubeowner.com/kbase_2/file_d.php?id=20

Anyway, this Cube document makes be think, that
  J1–J5  is the multiplicator (CPU speed)
  J7–J10 is the voltage
 (as it is on the backside and, like for the Cube, small jumpers)


Does anyone here possess a document that describes the jumper settings for the 
GC5-933-S2 (5-9310U) G4 upgrade by Giga Designs?
Or a source on the web that I didn't find yet?


Please help.
Cheers,
Andreas  aka  Mac User #330250

I'd say $200, for people who want fastest OS9 support. Mainly for the SATA.

IMO this is a very cumbersome workaround for a rare issue. If you eject drives 
before removing them you will almost never have problems.

Flash drives should be viewed as temporary or convenience storage ONLY. NEVER 
have the only copy of a file on one, because they do fail and fail 
unpredictably. 

follow those two rules and you can use them without worries.

Given that OO and LibreOffice now have native Mac interfaces, I don't know. The 
raison d' etre of NeoOffice was to get Open Office in a form that wasn't a 
horrible X-Windows program.

Re: DVD, Webcam, Pix, and Images: why are they soooo different

[Jonas Lopez]

Still asking the question: 

Since DVD plays so nice yet downloaded video items do not and Dan told us that 
this was because the downloaded file had to be worked on a lot prior to showing 
on the screen, we ask this question: 

Could a "good" server operator have done this processing for us and then 
downloaded the worked on file, so that the video would play just as good as a 
local DVD does?

Keep in mind that these new $9 per month movie services may have done just this 
very thing, since no way will the consumer pay for a movie that is of the 
general quality that is downloaded from the web and shown using Quicktime or

To clarify Bruce's post...

This has NOTHING to do with the media format.  CD, DVD, Blu-Ray... those are 
just media, plastic discs that basically emulate random-access r/o hard 
drives.  It's the codec used to encode/decode the video and audio data ON the 
media that's asymmetric.

The basic theory is that playback should always be easy, to allow use on less 
expensive hardware.  They try to do all the number crunching, compressions, 
optimizations, etc, during the encode process, because that's when the "author" 
(home user or professional) is going to have more cpu power available.

As to the primary codec used

CD-Video is either MPEG-1 or MPEG-2.

DVD-Video is MPEG-2.

Blu-Ray discs use MPEG-2 or MEPG-4 (mostly h.264) or VC-1.

Then there's those players that support DviX DVDs.  DivX is simply a flavor of 
MPEG-4.

Good question.  For now, no change as LibreOffice is too new.

Both LibreOffice and NeoOffice are valid forks of OOo.  Recall that 
NeoOffice was basically created because the OOo developers weren't 
amenable to having a specialized Mac OS interface.


I would guess, I think reasonably so...

1.  OOo will continue as-is under Oracle's direction.  Since it's not 
a cash cow, development will crawl and performance will continue to 
lag (especially since many of its developers have left).


2.  LibreOffice will get some great features and speed improvements 
over the next year or two.


3.  NeoOffice will continue offering their Mac-interfaced builds, and 
grab the best-of from both the forks.

Thanks, Dan, looks great!
What problems can come up? In the docs I only found that DiskUtil
doesn't work when that utility is active.

I would typically start it before mounting a (Fat32) USB stick or HD
that I only need to read from, and quit it right after.
That seems better for the file system than the "Clean up non-Mac
