I would exclude noad, since it does not touch the data.
AFAIK, the only file noad *writes*, is marks.vdr, which does not contain AC3 data.
vdrsync is a possible culprit, but it may also be a data error due to rain, etc.

I have burned vdr-recordings with AC3 sound using the burn plugin successfully.
I have not actually checked the AC3 sound (the DVD was a gift for someone
else who does not currently have AC3 equipment), but at least the creation
of the DVD did not crash.
