Just to be completely clear:
1. The PCM audio that you get out of your TiVo is
always converted by the box from a compressed format.
2. There is no PCM audio delivered to set top boxes through Virgin's cable TV network.
3. Dolby Digital decoders can sound different in different devices for reasons to do with cost, age, settings and the kind of device they are. That's what you're hearing.
4. The BBC News Channel in HD does not use Dolby Digital, the other BBC HD channels do.
