Very strange dvd+r problems!

[Espen]

I have burnt disk for over a year never had any problems at all to recently.

First I got problem with those verbatim disk, they seems to burn just fine with dvd decryper but didn't load in either my computer dvd or my two standalone players. Now I got similar problems with two Philips cmc disks. They was burnt without problems, but didn't load in my computer or standalon players. I have discovered that the disks that fail to play don't look the way they should. The written dye look strange it's almost like an inner circel of the dvd not has been written,( vary from 10-50% of the dye) It's a bit hard to explain, but haven't seen this on any disk before.

I don't know if it has something to do with my burner(Philips 228), but Ritek, Neo Premium(Ricohjpnr) and Verbatim 2,4x(MCC) still works great. This is starting to be very frustrating doing 5 coasters in a week, when not been doing a singel one in over a year!

If other brands of disk are working fine then it points to the media rather than your burner. Sounds like a bad batch of disk.

Does the write part of disc seem to fade gradually? It looks rather cloudy rather near the outer edge where the data ends. This happens to me often using Optodiscs, the first half of the disc is fine until it gets the that "fading" point, then that portion doesn't read at all. Sometimes my recorder registers an error, sometimes not but the disc still looks weird.

I have had some similar problems when writing at 4x. If I burn the same 4x media at 1x or 2x they work fine.

Are you running the latest firmware on that Philips burner? Because earlier firmware versions will not write to 4x media without errors.

I think you just answered your own question...

And yeah writing to 4x disc with your burner requires 1.51 or later firmware (as -jsl- said)

Oki, well I thought the Firmware could be the problem, but I burnt like 15 riteks 4x without problem. However I try to upgrade the Firmware right now, but it seems to be some problems. Flash tool can't find any target drive to upgrade. Is there another way to upgrade the Firmware?
