Is that HD-capable? HDTV seems quite common in NA, but currently in the UK there are very few HD channels, only available through overpriced subscriptions. It looks unlikely that there'll be any FTA/FTV HD until at least after the analogue terrestrial switch-off in 2012. > There's actually the perception with many in NA > that vdr doesn't work with budget cards!

If the Nexus-S requires replacement for HD/MPEG4 I wouldn't be surprised if its successor doesn't feature a decoder. The latest graphics cards support MPEG4 too, including H.264. Someone posted about a new DVB card which does have an MPEG4 decoder recently, but pointed out that it's only a reference design, not a production model. And it's PCI-E, so it doesn't look like the manufacturers are very keen to support old PCs. > I know from working regularly with Xvid / mpeg4 files that they > require a lot more processing power, and many pcs are older machines > dedicated to running vdr, not top of the line full fledged 4 ghz systems. I haven't noticed a big difference, although I've only encountered MPEG4 part 2 (DivX etc), usually at lower resolutions than DVB/DVD, as opposed to HD H.264. > I've never regretted owning my FF card, and would look for a FF mpeg4 card > if I was in the market.

Connecting a typical HDTV to a PC is pretty much the same as connecting a monitor, not like all the headaches involved in getting a decent PAL or NTSC signal from a standard graphics card. -- TH * http://www.realh.co.uk _______________________________________________ vdr mailing list firstname.lastname@example.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
