AC-3 is Dolby Digital. I've never had a stand alone DVD recorder but I would
have thought it unlikely your DVD recorder is encoding the recordings as
Dolby Digital. It would be phenomenally unlikely it's recording it as DVD-A.
Everything similar I've used such as recording TV to hard drive via a PC
Freeview card and capturing analogue video onto PC always records the audio
in some form of MPEG compression. A friend of mine has a cheap supermarket
DVD recorder without a hard drive which also records the audio as MPEG when
he records old videos onto disc via the Scart socket. If you burnt your
recording to a DVD and played it on a PC, programs like PowerDVD will tell
you what format and bitrate the audio is.
