Ok first off, the whole DVD-R/PS2 thing is rubbish. My ps2 plays back my DVD+RW disks without any hesitation. The only format that can't be played back is DVD-RAM (basically 'cos its complete crap

)
I agree that DVD+RW seems to be the recommened format, for the simple reason is that it's more suited to on the fly tv recorders IMHO. Personally I'd recommend the sony drive.
