After all of what has been said here, it seems that the only real solution is to recode the videos. If I can get decent quality, at better than realtime, as Reimer suggested, that would be satisfactory for now. As for the file size, I typically use a 4GB USB flash stick, but I have an old Creative Zen player that can become a good 16GB USB drive. Thanks for all the great info, though. I am an old school computer engineer (anyone remember RSX, CPM, VMS?). All of these different formats (codecs, containers, etc) get to be a bit overwhelming, especially when new ones are constantly being created (what was it I said about scientists who find a necessity? :-) ). Thanks again, ken
