I'll get the following error message from mplex:

ERROR: [mplex] Can't find next AC3 frame: @ 555776 we have c0f8 - broken bit-stream?

I've searched the sourcecode of mplex and found the error message in ac3strm_in.cpp. The error occurs if the AC3-Syncword of the current AC3-Frame is not 0x0B77 and the end of the stream is not reached.

I'll assume that noad or vdrsync has currupted the AC3 stream,

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.

...

because i have tried to demux the .vdr's with ProjectX and the AC3 causes no problems with mplex. The DVD i've created with ProjectX was not playable in my Standalone DVD nor with VDR's DVD-plugin.

The question i have is: Is it currently possible to burn vdr-recordings with AC3 sound? And how do i do this?

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.

Carsten.

The strange thing is that VDR has no problems playing the files, so ill assume that they are correct. (most of them at least) I don't know what VDR does with the stream that there are no hearable errors. As far as i remember, there was really good weather that day ;)
