I did not mess with the audio to make sure sound came out. I imagine<br>
some tweaking might be needed to get things "perfect" for ones<br>
definition of that. Why do you use such a large read ahead? I know<br>
it's been recommended in the past by some but in my experience that<br>
causes more problems than it solves.<br>

Suit yourself. Personally, I'd rather have the full power of<br>
mythfrontend available. If effort is spent on new frontends, I'd also<br>
prefer it spent on cross platform ones.<br>
