After burning a backup dvd-movie I always make a KProbe scan first. Normally the scan is good, PIFs 1-2, sometimes occasional 3. Then I check the disk in my standalone, a very picky eBench KH 6777. All of my (4x) burns were always perfect. Lately I tried to burn 8x with RicohJPNR02, fw BS0S. It started out really good, but the last part of the burn was a mountain, both in Pi and Pif, so the standalone froze on that spot. I tried CSTJ, CS0K but both firmwares produced PIF spikes to 4, resulting in occasional freezing. The best firmware for me so far is CS0M, it's the only one that gave me a perfect burn at 8x. I let my colleagues test my dvd's just to verify my own findings. At the moment I burn my backups at 4x, I want highest quality and I take my time to do it. :bigsmile:
From the moment BS0S came out last Christmas I changed the booktype to DVD-ROM and (to my surprise) it did'nt change back since. With CS0K, CSTJ and CS0M the setting in the EEPROM stayed DVD-ROM.
