I have been trying to figure out how to build a HD pvr using linux. My current thinking is to use the pchdtv card in a low end box with 200G of disk or so. Then it appears I can use the Roku as a network video server that can display the data on the video storage box. I'll probably use the linVDR sw to do the sw. I could not find a video card that looked like a good choice, plus the roku has no fans. So I can put the pc in another room & just network it to the roku.
Has anybody else tried something like this?
Is the video quality of the roku good?
Is there any difference in mpeg decoding for
stream MPEG by different decoders? Apparently there is a difference
between stream MPEG (from a ATSC tuner) and
program MPEG from a DVD. I know there are differences in DVD decoders.
I know, there are easier solutions, but I am a linux zealot. Besides the pchdtv card does not enforce the broadcast flag.

Thanks,
Mike
