Instead of rebuilding to 10.04 I decided to try Mythtv0.24+fixes with the 2.6.36 kernel. After some additional research/user-group posts I have managed to get my mythfrontend working pretty reliably with smooth HDTV playback (something I couldn't achieve before). There are a few glitches when moving from playback to menu but now in a much better state than before. Note, I upgraded both the backend and frontend systems to the same kernel & mythtv versions.
