I'm now using the Video2PC program to copy VHS to DVD. At the moment, it's really good, and I'm pleased with it. However, there is one thing - as well as copying to DVD it saves a copy to the laptop hard drive. It uses the file extensions of .mpg; .tms; .tdp. Double clicking on the file name should allow the file to open, but it it doesn't. Do I need to download additional conversion software, or do I need to change the play software (from Windows Media Player)?
I suspect that they are the project files for you video.
The program will have imported your tape into a mp4 file, which you have then editeded etc. It will then have generated a new mp4 file which it then uses to make the dvd.
