I bought these a while back when they were $10 for 25, knowing they were probably really CHEAP ( Price & Quality ) DVD-R's. I do notice that in these 50packs it does have 1x printed on the dvd. I did a test burn at it burned at 2x with no problems. I've burned a total of about 50+ on my nec2500A (stock firmware) perfectly at 2x, no coasters. All play back in my sony dvd player and PS2 just fine.
