The black spots is probably related to your source files. This is not uncommon with over-sized photos and MPEG2 files in Premiere Elements. The only sure solution is to convert to DV-AVI. http://forums.adobe.com/thread/415317?tstart=0
You can not change the audio properties when burning to DVD, Premiere Elements will burn to 48KHz Dolby Digital Stereo... not sure why you are seeing AC3 6 channels... see this from the PE7 tech docs:
"Adobe Premiere Elements can import Dolby AC‑3 audio in a stand‑alone .ac3 file with .vob (DVD) or .mod (SD-based camcorder) files, but it exports the audio from it as Dolby Digital Stereo only."
Thanks for the fast response - I still can't understand why it was fine while editing, but since exporting to DVD, that one section is black.
So, you are saying I WILL have to remove that clip and add again (once converted to avi) as then retrim and put back the markers?
(You just reminded me of another reason I've not upgraded - I have to do so many workarounds like this. Why can't they fix rather than force upgrade?!)
Yes, it is strange, these black sections seem to appear for no apparent reason... sometimes they only appear when burnt to DVD and sometimes they are seen on the timeline. But it appears to be related to the video format or photo sizes as I mentioned. Only way I know to get rid of them is to convert to DV-AVI.
By the way what did you use to view the audio format on your DVD?
I found the solution to the blank error - what had happened was that when I was trying to make the background, it said "drag media here to make thumbnail" (or something) so I did, but although it didn't work, what I didn't realise was when I dragged the preview image to the thumbnail, I had actually dragged the image right off the screen! But when I did "undo", it looked OK, so I didn't notice it hadn't undone the move. If that makes sense.
As that was the last thing I did, it didn't bother checking before burning. I found this because I started a new project to convert it, and thought "well, if it plays OK here..." and started experimenting. I only saw the video offset by accident!
As for the question about Audio, I was previewing in MPC Home Cinema, but you're right. because when I preview in Windows Media Player, it appears to be OK and says Dolby 2.0
Thanks for your help!
Glad to hear you got it sorted...
