Benq 1620 session fixation error

Postby seaegg on Fri Nov 19, 2004 1:49 pm

I tried burning a Maxell 8x DVD+R at 2.4x using DVD Decrypter & Nero and kept getting a session fixation error at lead in. I then tried burning the same iso file at 4x using DVD Decrypter and it burned with no problem. I then scanned the disc using CD-DVD Speed and got a score of 96 with PI errors: average 2.98 total 26298 PI failures: 0.21 total 1626 PO failures 344 which seemed to be right at the end of the disc. Is this a bad disc? I sure hope not because I bought a 25 spindle and this disc is like the 5th from the top.

Hrm... when I did the review on the BenQ DW1620, compatability with Maxell 8x media was pretty bad at higher speeds, but I didn't have 8x DVD+Rs and I didn't try at 4x. I *DO* have Maxell 8x DVD+Rs now, so I'll see if I can test it out for you later maybe tomorrow.

I chose another disc from my spindle and it burned without a problem at 2.4x. I then burned the same ISO again at 8x to the same type of disc Maxell 8x DVD+R. The scan results are below, let me know what you think.

Both scans are good. I'm used to looking at 8x scans on the BenQ though... but they should still be fine.

Am I right in assuming that the Benq 1620 will burn 4x DVD+Rs at 2.4x & 4x but will burn 8x DVD+Rs at 4x, 8x & higher but not at the slowest speed of 2.4x? I can't get it to burn 8x discs consistently at 2.4x. I either get a session fixation error regardless of the siftware I use or it simply ignores the 2.4x speed setting and burns the disc at 4x. The discs in question are 8x Maxell DVD+Rs. It also burns the Maxell 4x DVD-Rs (TY) at 4x only, then again that's the only write speed shown. However with +Rs it shows write speeds from 2.4 upwards.
