I've got a couple of classic video/audio faults on video clips that I wonder if I can fix in any way using software of some kind.
1. I've got some videos that have a great picture until there's lots of movement, at which point they do one of two things, they either "stripe" or they digitise into a mess of blocks.
2. Is there any way to correct audio synchronisation?
Be very thankful if anyone can help.

For (1) I believe you're out of luck. What you see is what you get - if the video track is messed up, that's all she wrote. The one thing I would recommend would be to use ffmpeg, decompress the video stream to raw video, and try playing that. If the problem is still there, you're out of luck. I can give more detailed instructions if you're interested in trying this.
For (2), yes, there are several things you can try. What kind of files do you have (wmv, avi, mov)? And what it the sync problem exactly - is the audio playing early/late throughout the clip, or is it in sync at some points and out of sync at others?

I had audio sync problems on AVIs. Somewhere I have or had a program that would re-encode the AVI and force audio sync. It's on the other computer, so next time I have it on (give me a day or two) I'll look for it.
