[mythtv-users] v30 unsmooth playback

[John Massengale]

I am getting jerkiness too on 1080i recordings from NBC on v30. I have an
intel motherboard running vaapi2. seems like if i change the deinterlace to
Weave it was better, but Bob or anyhing else looks bad. Other channels with
1080i the recordings are fine like off of PBS.
