Yeah I have put full movies on my 60GB black ipod ...
You have to convert them to H.264 format or Quicktime Pro's QMP4. Only these two formats are compatible with the ipod.
Converting is gonna take a while, so your best to set it to convert when you go to bed.I found converting the video format is slightly quicker using QT Pro ($30) than with
Videora free iPod video converter. After all - it was made for the job!
Once you have converted the video, transferring it to your iPod is a bit of a patience required task too, but not that bad - about 15 mins for most 90 min movies.
If you like the portability and style, then the 5G iPod is the way to go all the way ... I love mine, but if you are not a patient person, you may want to drop $150 on a decent portable DVD player.
