Audio problems on DVD

[greencroft]

I am using a Canon MV550i camcorder to record in car footage from car rallies onto DV tapes. I then upload these to PC using Pinnacle Studio Version 9.0. I am editing the footage here and have eventually worked out how to do title pages and even menus. I then go through the rendering process to create an image on the HD before eventually burning to DVD using a Samsung DVD RW external drive to burn onto TDK DVD-RW discs. The DVDs that this produces work absolutely fine on the PC when played using Nero Showtime.

The only DVD player I have is my old Sony Playstation 2 which plays commercial DVDs fine. However, with the ones I have produced, on each scene, the footage runs fine for about a minute, then the sound starts stutterring in and out, the sound then goes completely for about 20s, then comes back stuttering, then soon works fine again through to the end of the scene. The visual image works fine throughout.

Have I done something wrong? Any pointers gratefully accepted. I suspect a more modern DVD player to the TV might just work fine.

Another query - what do people do with their previous projects? I have an 80Gb HD and this gets filled very quickly with footage from rallies, each giving about 1hr15mins of footage. Can you back them up the whole project so it will be available in the future without having to go back to the original DV tapes?
