Video and Sound Glitch Playing Sequential Files

I authored a 720p 59.94 fps video on 25 GB BD disc comprised of ten individually rendered AVC video files of approximately 15 minutes in length each. The files were smaller segments of a continous video, so the video should play smoothly from the start of the first file to the end of the last. However, when playing the rendered BD disc, the player has a brief but noticeable audio and video glitch at the transition point between files, as though it's seeking the next file. Definitely noticeable and undesirable. Professional videos avoid this type of glitch. Any suggestions for how I can fix?

Note that I had split my video into 15 minute segments because Vegas was giving me problems with black clips when I first set the project up as a 2+ hour project on the Vegas timeline. The black clip problem went away when I broke the project into 15 minute segments. Not sure why, but understand many have the black clip issue.

1) Due to the differences of authoring and pressing commercial disks, they can be navigated more seamlessly than any burned disc, and the efficiency depends on the set-top player construction and firmware.
2) The way that seamless play is best achieved commercially and in one-off products is for the video that is created to be as one long single piece and is divided by (in logic) chapter marker placement for scene/chapter control.
3) If you are 'joining" separate video pieces in authoring by programming the end action to get the next video started - you will be subject to set-top player performance which could vary from fair to poor , but never perfect.

The player I was using was a Sony PlayStation3.

As I mentioned in my post, my initial project setup was for a single large file, but Vegas kept having problems with some video clips going black. Might work fine for one editing session, then be black the next. I'd have to delete and re-import the clip to have it work, then replicate any crossfades or edits, which on a project of that size got to be too cumbersome.

One of many disappointments with the Vegas and DVDA software. I would not purchase again.

You have not provided enough info about your workflow (exact source of video, codec used, any intermediate rendering?, etc) to indicate the source of black random frames in video.

But I would bet that is caused by your source, and/or the rendering codec process that you are deploying in VegasPro. Length of project to render also may have an effect.

I have not authored a BD with DVDA, but I will offer a likely cause.

Using DVDA for DVD, you can't have more than one video file (clip) in the same time line. I gather that is the same when making BD.
DVDA is making BD-HDMV disc not BD-J disc, although the results wold be the same.
Each time line is likely a separate playlist. The problem is that the BD spec. allows the player to stop when changing playlists.

As others have mentioned, the black screen / no audio time then changing playlists will vary from player to player. It can be as much as 1 to 2 seconds. Or with faster processors, less.

Hope this helps.
