As long as it supports the modulation & fec of your provider, yup. I'm using a skystar 2 and it's perfectly ok for dvb-s. If your channel is using s2, you'll need a dvb-s2 card. There are not that many hd channels using dvb-s (I can only see bbchd, itvhd, luxe tv, fashion tv), there are many more using dvb-s2, but I think most of them are encrypted.

I don't keep a list of dvb cards & drivers but you should know that dvb cards don't care if you're watching sdtv, hdtv, or whatever else. They don't care if the stream is mpeg2, mpeg4, etc. The only thing that is important is whether or not your dvb card supports the method the stream is broadcast (ie: modulation, fec, etc). The only exception is if you want to use a "full featured", or in others words a card with an onboard mpeg decoder.

It supports all refresh rates up to 75 Hz but the visual output looked always the same as in 60 Hz mode. Televisions have native 50 Hz support so the result is better.

I have a few VDR boxes and all of them now are using Nvidia cards and vdpau. I output the audio/video to my nice fancy tv with DVI->HDMI cables. It works great. I'm not sure what you're really asking though when you say what setup is ideal. That completely depends on _your_ needs & wants but the only people I know with 'juddery' playback only experience it because the video card they have doesn't really have enough horsepower for the higher end hd content.

En/na Gavin Hamill ha escrit: My current vdr-1.4.7 (compiled 2 years ago as of tomorrow!) is still serving me well.. I have a Technotrend FF DVB-C doing all the heavy lifting, but as time moves on and HD content becomes more prevalent, I'm thinking of moving up. Right now I have an EPIA 800MHz quiet PC with the Technotrend giving me lovely SCART RGB out... if I got a nice LCD TV, what setup would be ideal for driving the HDMI input? I don't have a nice lcd/plasma tv, so I don't use hdmi. I currently play hd content (from a handful of satellite channels, only one of them, bbchd, carrying real programming) on my laptop (1680x1050 resolution, a tad smaller than the full-hd 1920x1080), which has a nvidia card, using xine-plugin on the vdr pc and xine-vdpau on the laptop. With vdpau almost everything is offloaded to the graphic card, so it needs really little cpu, it's possible it could also work on your epia, provided you can add a pci/agp card with a suitable nvidia chipset and are willing to use their closed driver. I have to say that the result seems pretty good to me. Ati/Amd and intel will probably offer some hd acceleration in the near future, however I don't think they offer anything right now for linux. I found this benchkmark: http://gwenole.beauchesne.info/en/blog/2009/06/22/video_decode_acceleration_benchmarks Most of the content is still SD, and I am a real pedant about smooth video / interlaced output for scrolling text / live sports. Any time that I've played with vdr-xine or xineliboutput over my years with VDR, it's always been a bit juddery due to VGA timing not matching up with the TV.. is that improved any in the world of HD / HDMI? Again, I cannot tell about hdmi (though I think I'd get similar results), but on my laptop screen sd content is upscaled acceptably by xine-vdpau (the scaling and deinterlacing is done in hardware with vdpau). Horizontally scrolling text is not very good IMO. I your tv scaler is better than the nvidia one (though it has to be a high end tv set for that) I suppose that you can feed sd content through hdmi, though everybody is suggesting to scale on the pc and feed the tv with its native resolution.
