I just got a 1620 and flashed it to B7T9. When I run a Nero CD-DVD Speed Create data disc, it burns fine increasing burn speed all the way 10 16x. I have TYG002 (Taiyo Yuden 8X -R from Meritline, and use DVD Decryper for image burning) If I try to burn a DVD disc image (unfragmented, I just ran SpeedDisk before burn), it starts out fine, then at about 20% it goes to 0x for about 30 sec, the goes on it way, but never get above 12x. Even if it makes it to 12x it is only for a second or two before it drops back to 0x for a while (it mainly fluctuates between 3x and 6x, near the end stays around 3-4x). It takes about 12 minutes to burn a movie backup. The same thing happens with any image I try to burn with DVD Decrypter, Nero, BlindWrite, and Alcohol 120%. I have a few Memorex 8X branded PRODSICR03 +R, and they seem to burn pretty consistant at 12X. My problem is why do the TY burn the DataDisc test good, but any image files they ruin? I have some Taiyo Yuden +R's comming in next week (hope it's just that it likes +r's better). Any help would be greatly appreciated. OH, it is also the same with with B7P9 as well.
