yup, you'll need a camcorder. Anything which can record from AV input, only canon and Sony have a LANC controller . you could also hunt for an EBAY camcorder with a busted CCD/lense for cheap - seen them going for less than 50 bucks.
Another option is a videojukebox, archos or RCA lyra. The RCA lyra can record from an AVinput direct onto MPEG4 format. Quality, I heard is iffy, but It is lighter.
