Well I thought I'd cracked it. I persevered with HDTVtoMpeg2 for the editing, but this time outputting in the native transport stream format. This created clips and all in perfect sync when converted to avi, great i thought!
However, when these were joined in Vdubmod, only the first clip was in sync.
AVI is the way for me as my new DVD player is compatible to play them.
They also take up less room and the idea was to keep the whole process fairly
quick and straight forward. DVD format would mean authoring and creating menu's etc.
The case continues
Thanx guys
