2-hour DVDs

I posted this problem in the General Discussion forum under the title of Oops! because I wanted to reach the widest audience about our possible posting error.

But it also involves an on-going technical problem which I am repeating here as being the most appropriate forum. I hope someone can help us, as we are having trouble burning our VMX files when transfered to a PC. The solution for us is to burn them on the iMac, and that is where the problem is.

Our posting goof occurred while we were trying to follow Matt's instructions as  to the process of combining  mpeg4s into a longer DVD to play in Stowe. The instructions were fine, and we simply goofed, and  our apologies to all concerned.

Maybe someone  experienced in the ways of  Imac can help us solve our next problem. Using Matt's process, we can now combine two or more mpeg4s into a single file approaching two hours.  But  we need the DVD to be exactly 2 hours. We do this all the time with non-VMX shows on our PC by adding some short shows of our own we can edit in a way  that will end the  DVD exactly at the 2  hour mark.

 The problem is that I haven't been able  to do this on the iMac.  For some reason, iMovie won't accept the VMX mpeg4s or mpeg2s.  I think I should be able to do it in  the Mpeg Streamclip application I have downloaded, but I can't get it to accept my non-VMX mpeg2 filler shows.

 Does anyone have a solution for us as we really need to burn the DVDs on the iMac, and we can't have irregular TRT on the DVDs.

 Again my apologies for the posting notice  and my appreciation for any ideas how we can edit our own filler programs on the iMac to make 2-hour DVDs there to include VMX files.

Thanks.
