Some PBS stations have different programming on NTSC and ATSC, so we need both. Some stations compress the ATSC subchannels so much that NTSC has more resolution/detail. There are only enough bits for one HD or 2 SD, but some stations have 1 HD plus 2 or 3 SD, or no HD and 4-6 SD. :-( > > > but the people over at > > > linux-dvb don't seem to know anyone to help figure out why my ATI HDTV > > > Wonder doesn't work very well.. > > > > Is it the ATSC demodulator chip that isn't working? > > Yes, and I'm not sure why...

Could it be that the ATSC demodulator chip is filtering out some of the PIDs? > The Linux driver also has a bug in that they don't consistantly keep > two registers that control serial or parallel mode for the digital > video input, and the linux-dvb list completely ignored the report... Perhaps the Linux driver for a different card with the same chip would have different bugs?
