Guys, I'm storing quite a fair bit of vids from youtube in my Exec.
Basically, just a few simple steps...
1) using youtubex, save the youtube file with flv. extension..
2) google for a prog called cinemaforge (i think..). D/l and exe the file on your desktop. 3) convert the flv file to any form of media (wmv,rm,rmvb,avi) with the prog.
4) once the file's been converted, use pocket dvd wizard to change it to PPC format (take note of the framrate)
5) after the file's been done, AS the file to your ppc.
Seems rather lengthy but its actually pretty simple and straight forward

Enjoy
