When I bought my drive I spilled $9 plus about $2 shipping on a 10 pack of Legacy 4x +RW's. That was before I had visited this forum, or thoroughly read through scans in the BenQ forum (the drive I purchased). I knew they had to be low quality, and it was just an experiment.
Well, the Legacy's are INFODISC A10's, which are about the cheapest quality RW's around. Marginally effective, my BenQ 1620 has been able to make reliable burns with them for data and video.
I have a cheap ($28) Cyberhome that can't play RW, but the Zenith and the Daewoo combo units both play these with little or no trouble. The Zenith skipped a little on one disk, and the scan did have a large spike at 2Gbytes on that one, but the others have given me little problem so far.
I won't buy the Legacy again. Almost anything of reputation would be better, and I'd expect a player that can handle RW at all would do just fine with reasonable quality RW's - especially since these junk ones actually have done the job.
Players are picky, though - the more recent (no matter how cheap), the better off you are. My friend's Yamaha, which can't handle even SVCD's, is one of those that requires the book-type be set to DVD-ROM. That can't handle the RW either, even with the book type set.
