Using the ivtvdev X driver, if Xv isn't working for it then I need to know how to make it work *shrug*.
Already tried the drivers at the link you provided, with the problems already listed below, therefore using an older version of the ivtvdev driver.

Sounds like you're not using the XV accelerated framebuffer driver for
your PVR-350 output. This is causing your non-MPEG2 recordings
(although I wonder what is happening with your DVD playback, maybe your
DVD player software isn't using PVR-350 acceleration either?) to have
