I use Studio 9 and find it OK . Like all video ediying programs it takes patience to learn. Now if your Dazzle did work for a short then stopped I would investigate why or if it is dazzle or the software installation. I suppose that you are using XP so why not try a capyure into Moviemaker which is already on your computer. It may be that you only have moviemaker ver1 which is poor but can be update to ver2, which does improve it, however for your test capture it realy is of no importance. Just try a cpture and if it works then dazzle is proved to be OK and another area needs to be looked at.Like the settings you have on Studio 9. You can get a lot of info. from click here I hope that this helps.
