I don't know if i'm doing the right thing here, but it wouldn't have made any sense to reply to the last comment with a question. Is there an option to just ask a question; I didn't see it. At any rate, I bought confirmed ty 8x from Supermediastore. I use a panasonic dvd recorder and they appear to burn fine for awhile (in one case, over two hours on a 2 hr and 15 minute movie!), then the dvd recorder goes off. When I re-insert the dvd, it says 'not recognized', as if I was putting in a format it didn't play. I've had this happen with 5 discs out of about 60 so far. I could care less about the 35 cents for the disc, it's the wasted recording time I'm concerned about. Do you think this is a problem with the panny or...?
