yeah... about the starlogic...they are about the crappiest there is
I bought some CompUSA and StarLogic DVD-R, they both have MID of Princo, however CompUSA DVD-R works with 0048 and above (didn't try anything below 0048) as long as you burn at 1x, even though 2x is available, 2x result is mixed.
However, StarLogic does not work with 0048 for us doesn't matter which speed we set at, my friend and I both have the 1004, plus I also have the LiteOn 411s, and we killed about 10 StarLogic trying different things and drives and speed, mostly try on data(so some file works, some don't, nero verify failed, sfv failed). tried one movie backup(some glitches)
Now... if you upgrade to 0049 and 0050, I found that burning Starlogic will work slightly(very slightly) better, quality wise, checked with Kprobe, and burn at 1x of course... but it is still really only good for Movie backups, cause when reading at higher speed, it has a lot of errors, and PI/PO check with Kprobe clearly show much worst than the CompUSA disc. I don't know if it will work better with PS2 backup.
Good luck, and let us know the result... since I still have bunch of them sitting there, don't know what to do.
