I have the same problem on my NTL box. However I would say it is unlikely to have anything to do with the slow performance of the box. Unlike on a PC (which is the analogy used before), the decoding of the MPEG-2 stream isn't done by the application processor, it's done by a dedicated decoding chip. This is why when the box crashes (ie stops responding to user input) the sound and picture invariably continue (well, that's the case on my Pace NTL box anyway).
Furthermore, James' comment about stopping the silly discussion was pretty fair, unlike on a PC (to use that analogy again) the box hasn't got all the data laid out on a disk for it to play at it's leisure; it pulls it off the air in real-time. For a viewer to experience slow playback, the box would have to use a gradually increasing buffer to store the data between transmission and display.
If, for whatever reason, the box couldn't decode the stream quickly enough, it would just skip bits.

I've got an old Pace sky digital box from 1998 (with the old sky logo). It's very slow, and sometimes, but not often, the sound will slip out of sync with the picture.
Sometimes just switching channel for a moment will resolve the problem.
