Eventually we realised that our DVD burners need +R discs, so that was a start.
Then it transpired that P2E version 5.0 has problems with its music timing. It basically will not synchronise properly.
So we went back to P2E version 4.48 and, although the process is a little involved, it worked absolutely fine. The first burn was a bit jerky, so we repeated that at a slower burn speed and then all was well.
It was worth it in the end and the DVD is now winging its way to Macclesfield, hopefully to arrive tomorrow morning!
