[mythtv-users] PVR-350 TV and native Recording smooth, Transcodedand other video choppy

[Paul Fielding]

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 
  poor performance.

  I don't have this card, but I believe you can download the X driver here:
