For consumer SPDIF max bandwidth is about 2 x 20 x 48 kHz = 1.92 Mbit/s. E.g. encoded DD+ 7.1 bit stream fits there but linear 7.1 PCM doesn't. Highest end audio formats are at different order of magnitude. Dolby TrueHD can be up to 18 Mbit/s and DTS-HD Master Audio up to 24.5 Mbit/s those are passed only over HDMI in CE devices. http://en.wikipedia.org/wiki/Dolby_Digital#Dolby_Digital_Plus http://en.wikipedia.org/wiki/DTS_%28sound_system%29#DTS-HD_Master_Audio BR, Seppo In my case, I have a Samsung T260 screen with fibre out, probably SPDIF.

Should I get an amp that takes hdmi as input and passes video onto the screen? If the signal source is Blu-Ray disc then there is IMHO benefit with a HDMI capable AV receiver (excluding the early crap those were only dumb switches without audio tapping capability). Personally I've found the PCM or Dolby/DTS HD tracks sound better via possibly better mix than standard AC3 tracks. Audio coding improvement should not be that big. With just VDR DVB-C/T/S as a source there probably is no real advantage to upgrade to HDMI only over legacy SPDIF from TV to AVR setup. There could be usability improvements via CEC control channel though. And I don't know if CEC is supported by any PC HDMI hardware. (But perhaps in future VDR could get control from CEC from TV remote control too?) With my AV receiver HDMI menus it's also possible to select to route the audio to home theater or TV speakers like in your setup (with home theater system muted) though I never use TV speakers. They are pretty bad nowadays. This page might be useful http://www.hdmi.org/installers/index.aspx BR, Seppo ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
Re: [vdr] mdadm software raid5 arrays?
Alex Betis wrote: I don't record much, so I don't worry about speed. While there's no denying that RAID5 *at best* has a write speed equivalent to about 1.3x a single disk and if you're not careful with stride/block settings can be a lot slower, that's no worse for our purposes that, erm, having a single disk in the first place. And reading is *always* faster... Example. I'm not bothered about write speed (only having 3 tuners) so I didn't get too carried away setting up my 3-active disk 3TB RAID5 array, accepting all the default values. Rough speed test: #dd if=/dev/zero of=/srv/test/delete.me bs=1M count=1024 1073741824 bytes (1.1 GB) copied, 13.6778 s, 78.5 MB/s #dd if=/srv/test/delete.me of=/dev/null bs=1M count=1024 1073741824 bytes (1.1 GB) copied, 1.65427 s, 649 MB/s Don't know about anyone else's setup, but if I were to record all streams from all tuners, there would still be I/O bandwidth left. Highest DVB-T channel bandwidth possible appears to be 31.668Mb/s, so for my 3 tuners equates to about 95Mb/s - that's less than 12 MB/s. The 78MB/s of my RAID5 doesn't seem to be much of an issue then. Steve ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Subtitles are shown corretly both when viewing live tv and

recordings VDR just says that no subtitles are available.
I'm using vanilla VDR and the xineliboutput plugin.
Zimiq did all the hard work to pinpoint the faulty method:

En/na Seppo Ingalsuo ha escrit: With just VDR DVB-C/T/S as a source there probably is no real advantage to upgrade to HDMI only over legacy SPDIF from TV to AVR setup. If the only planned source is a pc (running vdr and, say, xmbc), would it make sense to bypass the av receiver completely and just decode the audio on the pc connected to the speakers? Or it doesn't make sense (since you'll need an amplifier for each channel anyway, so you could just as well buy an av receiver)? Just asking, since with wife, kids, and neighbours, I'll probably have to convince myself that the tv speakers are good enough ;-) Bye -- Luca ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

I suppose the benefit of going for AVR is better speakers management: levels, delays, response correction and subwooofer crossover filters. The effects are actually usable. I'm using stereo and surround modes from Onkyo AVR. I've been also quite happy with Audussey setup. A pure PC plus amplifiers (class-D modules) could be superior to AVR in those tasks but I'm not aware of such developments for e.g. ALSA user space or PulseAudio. Just asking, since with wife, kids, and neighbours, I'll probably have to convince myself that the tv speakers are good enough ;-) The center channel is really good for any TV watching. But my wife is not happy without a properly programmed universal remote. A watch VDR macro does all the powering and routing.

Re: [vdr] Replay Problems with Extension HD
Hi Klaus (and others) the replay problem is probably fixed. It was located in the hdplayer program that runs on the eHD. The fixed version should be available soon.

[vdr] Tuner switch when timer starts recording
Hello, With VDR 1.7.9 i often notice that VDR switches the live TV to a different receiver card, when a timer starts recording, although the second card is available. This causes a short interrupt in live TV. My system has two DVB cards, an old FF and a Tevii S470, and an eHD. Sample situation 1: the only activity is live TV on ZDF. Now a timer starts recording from RTL 2, which interrupts the live program for a short moment. Sample situation 2: the only activity is live TV on RTL. Now a timer starts recording from RTL 2. Nothing happens, because VDR correctly shares the transponder with live TV. I would understand when VDR switches live TV from the DVB-S2 card to the DVB-S card when it needs to tune a different transponder for a DVB-S2 recording, but since it can do DVB-S recordings from any card, there is no reason to switch live TV for such recordings.
