DVD Lab Problem.(No audio after 3rd chapter)

[Desperate Jip]

Hi Folks, I have a problem with DVD Lab and would be grateful if someone would take a look.

I ripped a film with DVD shrink and chucked it into my project in DVD Lab 1.3 (joining it into 1 vob file). When I compiled it all the menus and extras worked fine but my problem is with the main film. If I skip past the 3rd chapter I lose the audio, However if I just let it play through then its fine (but who wants a DVD that wont navigate through the chapters) and also when I skip past the 3rd chapter the "Title/Chapter Remain" on the display reads 00:00:00 so I know theres a problem somewhere. I then tried playing the files from my hard drive in Power DVD. This time when I tried to skip past the 3rd chapter the power DVD remote thingy went straight to the last chapter but the film was actually playing from the start. I also noticed that when I was skipping through the chapters in my DVD player, the further into the film I got, the longer the player took to index the chapters (if u know what I mean). Anyway, thats my problem, hope ive given enough info. Hope someone here can help...Thx ppl

Its ok I sorted it out....seems the vob file was giving DVD Lab grief coz it contained 2 audio streams (must have forgot to untick the Directors comments in DVD Shrink when I ripped the disc) and I only realised this when I let DVD Lab Demux the Vob b4 I inserted it into my project....oh well, as Roger Warters would say "all is well in the camp".
