This is how I understand it - the DVB cards are not doing any encoding
(just dumping the stream) and so the profile settings do not affect
things (same with hardware MPEG2 cards too I think). To save space,
you then create a transcoding profile to convert the MPEG2 files to
MPEG4 etc. (In the UK, I find that high bw channels such as BBC1
[15Mbps] uses ~4GB for a 2hr record, and a lower bw channel [6.75Mbps]
about 2GB for the same. I record in TS so that I can record radio from
DVB, this will increase the file size slighly due to the extra format
