serious quicktime issue, basic MOV codec corrupt? mac

[aceswild]

I've been trying to convert (re-wrap) a ton a of avis to movs for a couple of days now and it's not gone well. Final cut pro was running quite badly with them but it managed to do some if i gave it a few at a time. i didn't want to have to rely on it at the risk of leaving it over night and coming back to it crashed.

so i tried mpeg streamclip, which did the job but the videos came out looking interlaced. i tried to install ffmpeg but got lost.

I dont know at what point this happened, but a codec or something must have become corrupted, because now final cut crashes everytime i try to do save out one avi as a mov, and mpeg streamclip AND quicktime have both slowed to a crawl when i open an avi and so to "save as" - mov. before, they would both rocket through it, but now both are painfully slow. does anyone know what i might have done?
