Yes I agree.  My suspicion right now is that this has to do with the 
cx25840 driver which is not part of the pvrusb2 driver (we just use it).

Again, no surprise here.

While the USA is roughly 24 hours away from the switch to digital 
(right?) there are still a lot cable subscribers on analog and a good 
chunk of the rest of the world is still on analog (though not NTSC in 
that case).  So I'd have to think that others will have seen this.  I 
definitely didn't see it last time I tested it, which would have been 
just before the last standalone snapshot release.  On the other hand, I 
could have been an idiot and not noticed it :-)  I'm going to look for 
the problem now however.
