Cool! I am getting one of these. I am including an affiliate link here. This sounds like a scam post, but I really am going to buy this! 🙂
UPDATE: Piece of crap. Do NOT waste your time or money. There is a constant hum in the background of my sample recorded songs (side 1 of End of the Innocence, FYI). The FF and REW buttons are switched, so it took a minute to figure out how to get to the start of the tape. And, topping it off, it looked like it was about to mangle the tape. When I stopped the rewind and pulled the cassette out, the ribbon was twisted.
On the subject of converting, this site seems good for converting various digital formats from one to the other. They do more than just MP4 to FLV, but this is the link I'm using right now: MP4 to FLV Converter
