Well, I'm back... after trying everything and then some. Decided to uninstall everything again, deleted all files which smacked of nero in any way, ran their general cleaning tool, and re-installed the entire program from scratch. Started with Nero software which came with my Sony DRX710UL burner, a version w/VisionEX2 and worked upgrades incrementally to the most current. Got my first DVD burn with VisionEX3, and with a menu! Took 4 hrs 41 minutes as the program insisted on trancoding regardless of the file being mpeg2. Couldn't wait to view the result, everything seemed near perfect with exception of a chapter button refusing to be customized without crashing the program during menu creation - so I left it saying chapter 1 (not the end of the world). Fired the DVD up, hit the chapter navigation button, movie started w/music, then all audio vanished and it was like watching a silent movie. I made a log file this time... in case there is anyone who might know what went wrong? Here are specs from that log in case they contain information which reveals the problem - wasn't sure which part of the log was most pertinent: [18:08:30] ExpressUI ------<NeroVision Project Information>-------- [18:08:30] ExpressUI --- Project type: DVD-Video [18:08:30] ExpressUI --- Project video options --- [18:08:30] ExpressUI Video mode: NTSC [18:08:30] ExpressUI Aspect ratio: Automatic [18:08:30] ExpressUI Quality: Automatic [18:08:30] ExpressUI Resolution: Automatic [18:08:30] ExpressUI Sample format: Automatic [18:08:30] ExpressUI File type: MPEG-2 [18:08:30] ExpressUI Audio format: Dolby Digital (AC-3) 2.0 [18:08:30] ExpressUI Encoding mode: High Quality (2-Pass VBR) [18:08:30] ExpressUI --- Project space information --- [18:08:30] ExpressUI Used disc space: 3.00 GB [18:08:30] ExpressUI --- Project contents --- [18:08:30] ExpressUI Sample format: Automatic [18:08:30] ExpressUI Audio format: Dolby Digital (AC-3) 2.0 [18:08:30] ExpressUI Encoding mode: High Quality (2-Pass VBR) [18:08:30] ExpressUI Number of titles: 1 Discovered what might be wrong with the Pilates exercise videos I bought at a yard sale and tried to copy. Turned out to be an incompatible frame size - PAL?, tried to change frame size by conversion and to .avi to shrink it down, but haven't tried to burn it yet. Error message I got prior was: "The MPEG file screen size is 480X576. NTSC standard is 720X480" If anyone can shed some light on this, I'd love to hear it. Sent my email address to Craig, so far no reply. Sure hope he's in Germany right now working on this and gets back to us. For a newbie, I'm sure getting broken in to all this the hard way.
