I probably didn't explain the video problem well enough.
The original file was recorded in one session with several segments all of which becomes a TS folder via MacTheRipper. (I don't know any other method to covert to TS so that Toast can compile several of these folder with their segments). Numbering the folders to assign a sequence doesn't help with the segments in that TS file that TOAST arbitrarily assigns "main or extra".
When brining that TS folder into the TOAST window (Video >TS folder), that's when Toast "creates" the mains and extras which doesn't make sense considering the fact it should just show a listing of "main" movies, one for each segment. I realize that burning a unencrypted movie with bonus features those bonuses show up as extras when veiwing the option mode and these can be previewed and then unchecked if not desired in the final version burned by Toast. A valuable feature.
Perhaps there is another software product that will do this better than Toast. I've considered looking into Smith Micro and Aimersoft, but it seems that TOAST has been the favorite so far.
I've used the technique you've described to number audio files when burning an MP3 playlist. As a MacUser you've probably discovered that when iTunes burns a playlist to CD the names of the songs are converted to track 1,2, etc., however Toast will keep the song title but only burns the CD in alphaetical/numerical order.
Here's a couple of JPC screenshots of my problem that may be helpful. Let me know if they don't download OK. Thanks (pictures were inserted in reverse order...)
