[mythtv-users] Trying to record HD - sound issues?

[A JM]

This is kind of a 2 part question. I'm running Ubuntu 8.10 and am able to
view/record w/sound etc.already so I would consider this a working system.

A) when trying to view HD I get the following message on the frontend and a
green staticky picture and the frontend is freezing.

B) when I want to watch HD I have to "switch input" is this normal?

Thanks for any help you can shed...
