This could indicate that your computer is unable to process playback, either because your system is not powerful enough or because you need to render your timeline.
What type of camcorder did your video footage come from?
If there is a red line above your clips on the timeline, have you pressed Enter to render the clips? (The red line will turn green when it's done.)
How fast is your processor, what operating system are you using and how much RAM do you have?
Also, you say "when I view the video on my PC". Does this mean that you've output your video? If so, in what format have you output it?
The timeline was green, camcorder--Panasonic, memory okay, MPEG. I burnt a DVD and it works on other computers. I just tried viewing video in windows media center, it worked fine. But why not with my wmp 11?
Sorry. You really haven't given us enough information to be able to help you.
What happens if you play the DVD on a DVD player or on your computer's DVD player software rather than WMP?
I played dvd on my pc, it opens up with wmp. Choice of viewing shows wmp, quicktime, and windows media center.
Thanks people for your suggestions and tips. I got the sound to play. What I did was change the audio setting from dolby to mpeg and that made the difference.
Interesting. In NTSC-land, there are only two certified and allowed Audio formats for DVD, PCM/WAV and 100% DVD-compliant DD AC3 (can be 2-channel, or 6-channel). In PAL-land, one has the choice of either of those two, plus MPEG-Audio as an optional format, but that is falling out of favor and will probably soon be discontinued on newer PAL DVD players, if that has not already started.
All certified DVD set-top players MUST be able to play PCM/WAV, and 100% DVD-compliant AC3 (actually a flavor of MPEG-Audio with a difference). If you cannot play the AC3 version, then something must be getting in the way of the AC3 encoding process.
I also have loading issues with elements. I am using WMP vr 12 under windows 7. I have a corei7 920, ample ram and elements 8,
When I load an AVCHD file into the program the video and audio seem to load fine, when I play the file I lose the audio in around 30 seconds, Corel WinDVD9 player doesn't lose it audio but the volume is very very low, VEGAS has similar problems as Adobe, but WMP 12 is perfectly fine!!
