I think there are two different issues with audio disappearing:
1. Single-audio-track channels (e.g. channel 7 which has MP2 only in Sydney, Australia) appear to have two audio tracks when changing from two-audio-track channels (e.g. channel 9, which has AC3 and MP2). The extra audio channel is non-existant and so there is no audio when playing it back. This appears to only happen in live tv mode (not recorded shows). Changing from PS to TS has no effect.
2. Bad reception, or RF noise/interference (e.g. light switch, fridge turning on/off, etc) corrupts DVB stream. Sometimes this stuffs up audio for both live tv and recorded shows. For single-audio-track channels, pressing +/- won't make a difference. For multi-auidio-track channels, pressing +/- will change to the other track. Note that I always prefer AC3 audio, and when the AC3 track is corrupt, MP2 is the fallback - this is not optimal!. Changing from PS to TS also has no effect because I find that myth ALWAYS records all audio tracks.
David Whyte's earlier post appears to be incorrect (at least from what I see). Myth does not only record the primary audio track - it always records both tracks, regardless of PS or TS. (correct me if I'm wrong too!!) :)

I've seen the slow motion problem too, but only when i use livetv and change
from a channel that have 4:3 aspect ratio to a 16:9 channel.
And this only happens sometimes.
Exiting livetv and going back to the channel always fixes the problem.
