Umm, are you sure that the pcHDTV NTSC supports cable?  I wasn't aware 
that it was a cable tuner.  I thought it only did OTA (over-the-air) 
NTSC.  Just wondering anyone really interested in NTSC over the air?  I 
am only about 10-20 miles from our local stations and the reception is 
horrible.

I could probably test some things for you if you want to send the 
patches.  I run the latest CVS so, is possible, please send diffs 
relative to CVS.

Thanks, it is nice to have another pcHDTV interested developer.  I 
haven't done anything on the HDTV video side.  I have been spending most 
of my little available time on improving the overall Alsa support.  Next 
up, volume control!  I know not necessary with external 5.1 decoders, 
but some people like to control the volume through the Myth box.  Yes, 
OSS already currently supports this.
