DVD Architect - Subtitles - Problem

[Cunhambebe]

I've never had a problem with DVDA and subs, but now, I do have one. I frameserved my project from Vegas to TMPGEnc, encoding at VBR 8500 to 9500. I used this MPEG2 file to author my DVD as a test. I have 3 subtitles, French, English and Portuguese, video is about 3 minutes, sound is AC-3 5.1. In fact, I've prepared and burned the DVD 2 times and the problem is the same: subs are disappearing too often. I thought about 2 possibilities:
1. the bitrate may be upsetting the player;
2.the size of this project which is too small (I think the problem might be caused by what I describe in n.1).
What do I do?
Thanks in advance.

Sony recently rolled out a point release to resolve some issues - 3.0a. Might be worth downloading and installing this update.

Your bitrate is within spec, so any compliant player should play it without issue. I know tmpgenc used to have an occassional problem with bitrate spikes, but I though that was resolved.

Thanks so much for your help. I've already fixed the problem. I've just decreased the bitrate to VBR 9000 to 8000. The thing is, despite the fact the bitrate was within spec, please remember that I'm encoding only the video stream. That means there are other things such as the Sountrack AC-3 and the subtitles. The video was playing prefectly; in fact, I was having some problem with the subtitles exactly in a section of the video where there were some visual effects (where probably the compressor used a higher bitrate). I've supposed the problem (subs were disappearing) was caused by the increase of the bitrate in that section + AC-3 and + subs, what could raise the final bitrate too far from the safe rate. Same thing happens with Xvid movies. Some people like to encode their own videos as Xvid and they too often pay attention to the bitrate when they are encoding the video stream since subs and soundtrack will be multiplexed later, increasing the final bitrate/size. Hope this helps other users who have the same problem. By the way, my DVD Architect is v. 2.0a and it works perfectly. Thanks for the input on DVDA 3.0a.
