I just did that. Unfortunately, it found nothing.

OK, I'll admit it. I'm scared.

I'm not a programmer. I looked at those pages and don't even have a clue 
what I'd do with that information, let alone have any faith that I 
wouldn't break my entire system.

I guess I need to wait until these changes/fixes make it into MythBuntu. 
Does anyone have any idea how long that might be?

Thanks,
