Even still, Kirk, it would be very helpful if you could confirm analog video functionality of your pcHDTV 3000 board, using either 2.6.15-rc3, or v4l-dvb cvs on top of any kernel version. ...But before that, please first try it in your current configuration. I do not have this board, and there *IS* a problem with it... Based on the tests done by Gene and Don, it looks like the regression is inside the v4l code, although this doesnt make any sense, as other cards with similar hardware are not affected. I don't know any of the specifics about this board, besides the fact that is has OR51132 (irrelevant - the problem exists even without cx88-dvb loaded) Thomson DDT 7610, and a cx2388x chip. I have two cx88 boards of my own - FusionHDTV5 Gold, everything works fine, both analog and digital. FusionHDTV3 Gold-T, using Thomson DDT 7611 (same as 7610) , and digital works, but the analog tuner is completely broken, regardless of what kernel version, regardless of whether I'm using Linux or windows, and it used to work a few months ago. I think my hardware is fried, but since Gene is able to restore functionality by a cold boot into 2.6.14.2, it makes me think his problem is because of bad code, where my problem is due to bad hardware. All I can think of doing next is to have Gene, Don or Perry do a bisection test on our cvs repo.... checking out different cvs revisions until we can narrow it down to the day the problem patch was applied. ::sigh:: Who wants to do it? I'll give you detailed instructions if you're willing.
