    I was told that PC Club had some 1x Generic media for sale that burns at 2x speed (cost = ~80 cents/DVD-R). I used ADVDInfo to test my DVD-R media to see which brand it was. I was told that the 2X speed would be with Sony media starting with A2VK430. My 1st batch of 25 disks worked great at 2x speed. But I bought three more packs of 25 with the A2VK430 code and they are burning at 1X speed.

    Here's my ADVDInfo results:

    1st batch (typical code: A2VK4309L262 300375) that worked at 2x speed:


    2nd batch (typical code: "A2VK4307L082 08882" or "A2VK4307K202 05857") that didn't work at 2x speed:


    I was told that if:
    -it had the A2VK code
    -that the writeable side was blue
    -you could see through the media

    Then it was a Sony. But these subsequent batch of 25 disks don't follow this rule and only burn at 1x??? Can anyone shed some light on why I've manage to buy 1x "Lead Data" media instead of "Sony" media???????

    Here's some info on what I'm talking about:Sony media PC Club feedback. Also check out my PC Club links above thor this type of media feedback.

    BTW, the PC Club sale was for a pack of 25 disks for $19.99.

  2. From what I've read, if the ID says Sony, then it'' burn at 2x, if it says anything else, it burns at 1x.

    Yes, after running the ADVDInfo test it becomes much more obvious. But isn't there a pre-purchase method of finding out whether 2x or 1x??????

  4. Ok, I have done some extensive research on these Generic DVD-Rs from PC Club and have found a way to 100% positively identify whether or not it is a 1X Lead Date disc or a 2X Sony(Possibly Lead Data 2X disc found as Sony by the burner). It is a Sony 2X disc if the code on the inner ring(not the plastic hub ring with black writing)is K1-3083 10MAK. If the inner ring code starts with an A1 it is a 1X Lead Data disc. The black code written in the hub ring doesn't identify the two discs properly because I have seen Sony's and Lead Data's share the same A2VK... codes. The neat thing about this way of identifying them is the fact that you can see through the 50 pack plastic case and clearly see if you look carefully their inner ring codes(Remember inner ring is the unwritable ring on the outside of the hub ring on the top of the disc). My first 50 pack has about 40 Sony 2X discs and 10 Lead Data 1X discs in it. I have burned around 10 Sony 2X discs and 5 Lead Data 1X discs flawlessly on my Cendyne 4X(Pioneer DVR-105) and had only one coaster which might have been a buffer underun problem since I was doing extensive work during burning.(BTW the coaster was a Sony 2X disc) The physical difference I could tell between the Sony 2X and the Lead Data 1X discs is the Sony's purple dye goes a mm closer to the outer edge of the disc then the Lead Data 1X disc. Other then that they look and feel exactly the same. I went down Saturday to get a second pack hoping to luck out, but they didn't have any Sony's with the K1-3083 inner ring code, so I settled for the A1 Lead Data 1X discs since they were only wanting $39.99 for a 50 pack. All 50 discs in my second 50 pack are Lead Data 1X and about 10 of them or so have very small bubble on the top of them. These bubbles are nothing be worried about since they aren't affecting the dye. All in all I haave found both the Lead Data 1X and Sony 2X DVD-R discs from PC Club to be of excellent quality and they should be very durable as time goes on and for only 80 cents a disc you can't go wrong!

    Thank you this is the information I was looking for. This appears to be the fool proof method of disseminating between the desired Sony 2X media and 1X media. My disks confirm your research.
