It is pretty strange. I brought both up and started a capture, then
compared the dmesg messages from that
module. The only differences were

diff -C 5  old_pvrusb2_module_short new_pvrusb2_module_short
*** old_pvrusb2_module_short    2008-03-09 16:52:38.000000000 -0700
--- new_pvrusb2_module_short    2008-03-09 16:52:03.000000000 -0700

in the initialization.
The settings

hblank 122, hactive 720, vblank 26 , vactive 487, vblank656 26,
src_dec 543,burst 0x5b, luma_lpf 1, uv_lpf 1, comb 0x66, sc 0x087c1f

are the same as are the clocks, etc.

What is different is the  X-0044: in the dmesg messages. For the old
module, the X is a 2
For the new module, the X is a 3. Does that mean it finds it at a
different address?

It is not obvious how what I see above would shift the vertical
interval, but the problem is really there.

Is there any chance it could be the mpeg encoder? I put debug=1 for it
in modprobe.conf but don't see
any messages from it at all anywhere.

I always get these kind of problems.
