All the PVRs just write the MPEG to disk exactly as it's delivered by the DTG broadcaster (MPEG2 filtered transport stream format). No PVR (apart from Tivo) includes an MPEG encoder so there's no possibility of re-encoding.
(actually that's a white lie the 4TV boxes have a software MPEG re-encoder but it doesn't operate in realtime - it takes several hours to post-transcode an original one hour recording).
The radio also arrives as MPEG2 transport stream but once you copy it to a PC there are tools that can extract the audio PIDs from such a stream and re-encode to a "standard" audio format like MP3 or WMA
