Ok, I’ve already posted some messages regarding my trouble with the latest firmwares. Now I would like to go in some depth, hoping to help someone else as well.
As I said, the trouble is in -R burning. It’s not a matter of average POs or PIs, but rather of very high spikes. Maybe I’ll try to post an image later, but imagine to have a disc with average PI lower than 50 and average PI lower than 1, but with many spikes of about 500 for both. Sometimes the disc is readable anyway, but as spikes get very frequent (which sometimes happens), it becomes even unrecognizable. I get the same behaviour with any burning program (Nero, Alcohol, RecordNow) or media (even Verbatim TY and Memorex)
Now, the question is: is there a specifical known reason for these spikes, both hardware or software related? I’ve come to the conclusion that it depends somehow on the level of buffer memory, but I’m not sure about that. Anyway, any help on improving the situation would be greatly appreciated!
