Help with multi angle problem......

Im making a DVD that at certain points in the 40 minute film it has an extra angle that the user can select. Heres the problem i have.

Using Vegas 6.0d and DVD 4.0b

I have both cameras on 2 seperate timelines in Vegas 6, ive cut and trimmed the second camera timeline B so i have 3 small pieces that are the 2nd camera angles, these are totally in synch with timeline A within Vegas.
Ive rendered out to DV timeline A ive then rendered each of the clips in timeline B.
Ive put timeline A into DVD architect and then inserted the 3 timeline B clips at the EXACT time and frame number that they were in in Vegas into the second video track, however they are not in synch and are between 7 frames and 30 frames out, each one is out by a different amount.
Both Vegas and DVDA are set up with the exact same project properties, PAL Widescreen.

Its very hard to synch these back up in DVD A if not impossible.

Anyone know why this is happeneing ?

help appreciated.

I've only played briefly with angles in NTSC land and it seems to work OK... Maybe a quick test would help using mpg2 instead of avi? I think Vegas does I frames at markers but maybe there's a glitch in DVDA? If no one posts that's done angles in PAL WS, maybe emulating stories would work?

You'd add your alternate scenes to the main timeline (close to where they'd appear) and render mpg2 with markers at both ends of alternate clips.. Import that into DVDA in the tree at left, at the same level as menus .If you need scene menus delete existing markers, set regular chapters for scene menus and generate scene menus. If needed add chapters at beginning/end of alternate scenes. Note chapter numbers for alternate scenes. Add title to menu twice & render DVD to hdd. Open in PgcEdit and Edit PGC cell lists for both titles.

It does roughly the same thing as angles, with a little extra flexibility since you can use whatever audio you insert at the timeline in Vegas. The downside of course is you don't have an angle button, though could add a BOV. It is a bit more common than angles I think -- maybe the most well-known example = Wedding Crashers.

I have not done any PAL projects or multi-angle projects since DVDA3. I have not seen any multiangle changes in the DVDA specs so I assume they are basically still the same. First, DVDA uses what is called mixed-angle, an enhanced form of multi-angle. The alternate angle(s) video do not have to be the same length as the normal angle video. The alternate angles can be added at any point along the normal angle and must be on a frame boundry. The mixed angles should not be mpeg and must be assembled (positioned) in DVDA not Vegas. DVDA has to render the mixed angle mpeg. You now have the added option to use BOV to change angles. This thread is an oldy but goody. HTH
