Is cursor 2x DVD-R (GSC001) reliable?

[Smile_M]

Hi, I seached all the net using google and found only one japanese page stating that the media is good. However the ones I found have a different code and writes at 1x. This Cursor that I have writes with SONy DRU-500AX at 2x without any problems.

Here is the code:
00 6A 00 00 01 40 C1 FD 9E D8 50 00 02 87 0D 13 .J...@....P.....
88 99 80 00 03 47 53 43 30 30 31 00 04 00 00 00 .....GSC001.....

The ones I found had the same code except
.B...@....P..... insted of .J...@....P.....

Are these DVD-R's any good?

My Cursor DVD-R are for Chinese market I guess.
Here is how they look:


Anyone tried these?
