When you created your project, did you select the Settings for a Hard Drive/DVD Camcorder? This is very important.
How did you import the video from your DVD to your computer and into your project?
Are you allowing the video files to fully conform before you begin editing? (You can watch the conforming progress in the lower right of the program's interface.)
Have you seen my free 8-part Basic Training series of tutorials at Premiere Elements support site Muvipix.com?
well, it's tough to answer some of your questions. the project was created by loading old vhs tapes into a sony video cassette/dvd recorder. I created the dvd there (dubbing it was called). the dvd plays on all my computers and dvd players.
so i downloaded the dvd contents to a file on my laptop (windows 7 64 bit); then using premiere elements 9, i clicked Get Media. Chose the file of the video. It downloaded to premiere in 5 separate clips. One does not play any audio and freezes after 30 seconds. The others play with sound.
As for "conforming" –Adobe did its thing...i waited until it showed the clip in the box.
I've scanned your basic training series, but none of the segments seem to address this issue.
The main problem is likely that you are using an inefficient method of digitizing your video -- burning it to DVD and then ripping the DVD to your hard drive and forcing Premiere Elements to conform and convert it. You'd be much better off using a direct digitizing method that creates DV-AVIs, as the ADS Pyro AV Link described in the FAQs to the right of this forum.
With the method you are using -- particularly since you are apparently not using the correct settings for your project -- there are any number of places things could go wrong or an incompatible file could be produced.
Sorry I can't be of more help.
