Plug in the camera, open up a terminal as root and type:
If you don't get any errors, then grab a program called dvgrab from www.freshmeat.net
and get it installed. Once that's done, open up a terminal as root again, and type:
dvgrab --format 2 /path/to/save/movie
No extension, it'll throw one on there. Now wherever you saved that to, you have RAW video, so you'll surely need/want to compress it, so grab mplayer from www.mplayerhq.hu
and install that, then use something similar to this from compressing:
mencoder -ovc lavc -lavcopts vcodec=mpeg4:vhq:vbitrate=1800:vme=5 -vop scale=512:340 -oac mp3lame -lameopts abr:br=160 -o compress.avi RAWVIDEO.avi
Sorry this all will seem a bit advanced if you don't have any knowledge of linux, but it gives you the raw idea of what you need so you can fine tune it to your needs.
Feel free to respond back, I'll be happy to break down things as you need them.
