Video
Initially, the only video I've viewed on the 8350 are a few tv shows I've recorded straight from my tv to the unit & cradle. I've since gotten motivated to try to transfer video in some different ways. Here's a quick rundown of my results:

-DVD player out to unit & cradle through RCA connectors: no problem -Next I took ~15 seconds of avi footage, imported it into adobe premiere elements 2, movie -> export, microsoft avi format, video settings -> divx 5.2.1, then created the file. The resulting file played fine in my computer. I then transferred it via usb to the 8350 and tada, unsupported file type. Went back and tweaked my settings to make sure none of them exceeded vosonics listed specs, tada, unsupported file type. Tried some different codecs (various microsoft mp4 codecs) all with no success. I even changed all the microsoft codec files to .mp4 file extension- still no luck. I then transferred one of the vosonic made files (the file recorded from the dvd player)into my computer and tried to mimic it's specs as much as possible, still no luck. I'll try again when I get the chance.

A couple other notes, I use a PC and know little to nothing about Macs so I wouldn't have a clue what you can use for file conversion. I do know that an excellent place to look for anything having to do with file conversions is http://www.videohelp.com/ . It was there I found the links to the k-lite codec pack which has all the codecs you need for your video editing program to use to convert to divx, etc.

I also haven't installed the magix software that came with the 8350; I've already got enough codecs and editing programs installed on my computer- I don't need anything else to slow it down/ make it unstable.

My fallback position is I've got an ATI all-in-wonder video card in my computer. I figure if I can't export any video files correctly through conversion and usb transfer, I'll connect my RCA jacks into the ATI card and record off there.

dpreview's storage and media forum is also a great place to learn more about this and many other personal storage devices (PSD).
