Subject: Variable audio delay in BBC HD TS files (ITV HD TS files are probably the same).

I've taken 4x30 second samples from a 1 hour BBC HD programme and put them through DGAVCIndexNV.
The audio delay value (in the ac3 filename) comes out at -1104ms, -1016ms, -1072ms and -800ms.
If I run the 1 hour TS file through DGAVCIndexNV the audio delay comes out with -1104ms (same as the sample from the start of the programme).
I just wondered if you were aware of this. Maybe DGAVCIndexNV could use the average audio delay.
This might be related to the recent change over of the BBC HD encoders where the audio delay has shot up from about -50/-70ms to around -1000ms. I can send links to the TS samples if you want to check.
