This solves the problem of dashboard timeout when DVD+R DL bitsetted is inserted.
Problem is not about cheap media or laser pot, is not in reading at all, is only about media check routines, so skipping some checks does the trick.

About not bitsetted media, I've only 1 crap not-bitsetted DVD+R DL found in trashcan, it doesn't read the SS, maybe it works for you.

apply the ppf patch to the un-encrypted firmware v47, then encrypt and flash sector 90034000

something like:

flashsec47_win K patched-e.bin 90034000 1000
