Looped Motion Background blacks out when audi added

Call me crazy.
I have a 5 second loopable .mov file I want to use as a background.

This works fine, looping forever. No blinks, black-outs or glitches.

Add an audio file as background audio and the audio plays, but the
background no longer loops.

I go to vegas and create a 30 second extended version with the audio
attached and render out of vegas. Using the new file name for Background
audio and video, the video blinks a black frame or two then loops. No glitches
in the aidio.

Return to vegas and use the orig 5 second video length and edith the
audio to 5 seconds. Re-render in Vegas and and no change. Same problem
only it just happens at the loop point.

Any suggestions ??

FYI
The problem is format independant.
.mov .mp3 .mpg .....
I have DVDA 1.0c
and Vegas 4.0c.

win xp pro all updates etc. etc.

Is the audio longer than 5 seconds? If so, after 5 seconds the audio will be black until the end of the audio. Once the audio loops, you will again see the video for the 5 seconds which will then turn black once again while the audio continues.

To get this to work correctly, make the video the same length as the audio.

Thats the rub jetdv, I edited the audio and video to the frame with the highest resolution
available in Vegas. I tried using files with audio attached and a & v in seperate files.

Same result. a flicker at the loop point.

The menu looping problem centers around the length calculation made
by DVDA and the file length created by Vegas.

See if you can recreate this on your system.

Start with any .mov 'video only' file 4:29:00 in length.

Place it on a video track in Vegas and it consumes
00:00:00 to 04:29:00 on the track.

Render the track to any DVDA format.

Take any audio file and render it to any format
using the same in and out points as the video
00:00:00 to 04:29:00.

Go to DVDA
In the Media explorer window, look at the file details
displayed below the window when you highlight
the original 04:29 .mov file,
the vegas rendered file reads 05:00 as does the
audio file 05:00 in length.

Without any files selected as background video or audio, the
auto calculated length of the menu reads 00:00:00:004.

place the original .mov file on the background video selection box
and the auto calculate time reads 05:00:000

add the edited audio file and the new calculated length reads
05:00:016

drop the vegas rendered video file on the background and replace
the .mov file with the Vegas file.

The calculated length stays the same. 05:00:016

Preview the DVD and the menue blanks at the loop point.

Uncheck the auto calcuate box on the main screen and
change the length to 05:00:000 and preview the
DVD again.

The loop is seamless.
