Recompressing AVI's to save space on your playbook
I wanted to be able to recompress my avi files so I could put more on my 16gb playbook.
I found a great program - and its FREE! Available for Windows only I think.
AVI Recomp
I compress my 1/2 hour shows (which are really 20-22 minutes) to 95 mb and my 1 hour shows (really 40-44 minutes) to 190 mb. It doesn't recommend going lower than 1/2 the size of the file.
This way I can have 9-10 hours of video on my playbook and only use up 2 gigs of space. The quality is still quite good as you are only watching on a 7" screen.
