A have a Samsung ms25 flashed with xtreme 5.2b.
I have not tried the elastic band trick. I thought this trick was for old worn out drives. (IMG:style_emoticons/default/sleep.gif)
Lately there has been a lot of complaints about backups and orignals not fully working. I'm wondering if Microsoft has started their destructive anti-firmware flash. (IMG:style_emoticons/default/ph34r.gif)
Why would they combat your ability to play backups by removing your ability to play originals as well? That would only create dissatisfied customers who won't spend their money on MS products in the future. MS is all about repeat business (buy windows before, you'll buy it when a new version you like comes out, etc), and they're probably much more concerned with piracy of windows than xbox, otherwise prices would be higher, and while the number of pirated games may be larger than in the past, so is the average amount that a game will sell.
Now to your problem. I'm almost positive your laser is either dead/dying or in need of a POT adjustment. Do you have a multimeter? If you do, take a calibration reading of your CD and DVD POTs. Stop re-flashing your firmware; that's not going to affect it unless it's flashed wrong.
