Thx for replying
Should have mentioned..Its just a clip i use to test, its an xvid with 2ch ac3 audio 3.30 mins long.
Have tried many different avi sources with both ac3 or mp3 audio. The moment subs are involved the batchmux plugin fails.
To sum up.
default dvdauthor and muxers with subs =ok
imago with subs =ok
imago+your excellent ac3 plugin and subs =ok
Batchmux =ok
Ac3plugin+batchmux =ok
batchmux with subs=error
Ac3plugin+batchmux with subs=error
