I installed an HD PVR a couple weeks ago  on a new install of Ubuntu
12.04 and Myth .26 and am now having no problems. I did have to install
the 1.5.7 firmware that is recommended in the wiki to get rid of colour
and lip sink issues. My set up is a AMD quad core 9750, Nvidia card,
Microsoft ir blaster/receiver, and a satellite box. It does take about
10 seconds to change channels but 8 seconds of that is the ir blaster
doing its thing. I'm using the component video input to the HD PVR, I
did try the composite and S-Video and the video and audio wasn't as good
as my Hauppagge 150.

Maybe if you share your setups it would help.
