I just got my pchdtv hd_3000 card to record to disk about an hour
ago. Recording doesn't seem to take up much CPU as the HDTV
signal comes over the air mpeg ts encoded. Playback is another
matter. I have an 1800 mhz P4, and it can play back the lower
resolution digital without any problems full screen. The 1080i
stream will play back as long as I don't try to scale it, but I don't
have a monitor capable of handling the full resolution connected to it
at the moment so I don't know if my poor slow computer can handle it if
it doesn't have to scale. Oh, and I don't have sound working yet
so there is the possibility of that being the straw that breaks the
camels back. Oh, and I should mention that I have one of the
radeons with open source support for hardware acceleration, and that
may be helping me a lot to make it possible with the speed of my
CPU. You can play back the recorded files with a stock copy of
xine from sarge. There is a test sample at
pchdtv.com in the
downloads.
