Yes. And looking at the article again, I found that they did actually give the bitrates of the sources they used. The H.264 1080p was 10Mbit/s. So multiply by four for a high-bitrate H.264. So their x2 FX cpu would not be fast enough. Their mpeg2 was also only 1/4 of the max, so multiply that by 4 as well. > Such a content is not used anywhere, so don't > worry. Not used anywhere? So where did they get their video? Mpeg2 and mpeg4 have the lion's share today, but h.264 will become more common in the future. > I made a test with the videos i've got, how it looks under Linux: The last I read, the linux software cheats and throws half the data away. :-( > But if you're targetting more technically based audience, they rather do > a compromise between quality and size and 720p is the winner. 720p is better for fast action, 1080i is better for showing fine detail. But I have yet to see any source material that is available in both formats. So you are stuck with whatever format is offered. If the program you want to watch is in 1080i, you have to decode 1080i, even if you prefer 720p. > A) stick to PC LCD: you get full 1080p, but its 24".

Mpeg2 is a must have. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
