How do I save clips from DVDs as MPEG/MPG/WMA?mp4 etc onto your PC
Another question I asked a while ago but didn't get an answer was when you take a DVD screenshot the picture moves with the DVD and when you take it out it goes black, how do I stop this?
You can use various programs to convert from DVD to mpeg. Search google for keywords such as "dvd convert mpeg".
For capturing images from a DVD, power DVD should come with an option built in to capture. Do this rather than taking a screen capture via an image editing program.
You'll need some sort of "ripper" to extract video from commercial DVDs, though if you have a video input card it might be possible to use this. Take a look at www.videohelp.com for lots of info.
Re the screenshot, is it the version of PowerDVD that came with your computer? Quite often they will come with a "cut down" version that doesn't do screenshots properly...
