When I got my PVR-250 a couple months ago I had a same issue and after many experiments noticed that tuner for TCL 2002 was set with frequency off by 1Mhz and figured out a hack to correct that. I sent the following to v4l list a couple months ago but only got one response back with positive result and no response from any developer. If this works for you (and hopefully more people) I like to pursue the issue further to be corrected there so I don't have to keep on patching tuner.c.

Elsewhere it was noted that this newer rev card uses TCL 2002N tuner different from former revs and not supported by released V4L. Then I found the support in recent CVS snapshots and tried video4linux-20040927-171556 and it somewhat worked, but the frequency setting were way off almost by 100Mhz. While looking at it further today, I noticed that there are new snapshots with changes in this area so I tried 20040930-141712. Much better but not quite. Now it is consistently off by exactly 1Mhz for all the channels (330.25 to watch 331.25). Looking at the bytes going across and seeing what's happening in set_freq, I modified the IFPCoff for the tuner to 716 instead of 732 and now it is right on. Without understanding those numbers I doubt this is the right fix. I'm interested in having this card work with V4L off the shelf, so if somebody knows a right way to fix this, I'll be glad to test patchs and/or gather more information on my card.
