When trying to load the resulting TS files into my usual editior VideoRedoTVSuite4, it fails saying it cannot handle MPEG-1 audio streams. Loading the files into its quick stream fix tool shows this:

Setting the record format back to TS, the files load without problem. Under TS Record Options, nothing is checked.
Further to this, I also have a second copy of DVBDream installed with which I record from satellite using a TeVii S660. This doesn't have the same problem: the MPEG record format is set and HD recordings default to TS which load and play fine.
Here are two files recorded from Freeview:
MPEG record format set, TS file recorded (15MB)
TS record format set, TS file recorded (15MB)
One other issue, no HD files play audio straight away (DTT or satellite) unless they've been through the video editor.
