I have patched my LDW 451S with the newest 451@851 firmware.
After that it didn’t recognize medias at all… and if so the reading speed was very terrible.
So I decided to flash it back to original firmware.
First I tried GSB9, newest one, original version. Same problems, but better reading speed.
Then I tried GSB7 optimized-patched for DVD reading speed, same as with the GSB9 here.
It recongnizes Medias nearly most of the time, but reading speed is terrible at the beginning of a burnt DVD for example.
All DVD-R’s I have burnt so far are not radable fast now. If it were Data DVDs it wouldn’t be a big problem but they are Movies, so it is alot annoying when the film and audio stutters or stops completely at all because of that reading speed.
Please excuse my broken english… ^^
