Hi,

i just upgraded my LG GSA-H54N drive to the newest official 1.02 Firmware, because i am suffering a very strange problem. I have burned some different DVD+R9 media and have some quality problems. I have tried MKM-001 MKM-003 and CMC MAG D04 discs. Even though MKM-001 is only a 2.4x media, i cannot select 2.4x when i try to burn this media. I always get this result (just additionally offering 6x, 8x and 10x for MKM-003):

Whatever media and firmware i use for my LG, it is not offering me 2.4x write speed, what should give me the best write result. I also unpacked the new 1.02 firmware and looked at it using MCSE and it is always showing me 2.4x for all 3 media codes. I just can not select 2.4x when burning. What am I doing wrong?

Thanks in advance

This seems to be a feature of the H5x drives, the H50N behaves the same. MCSE reads only the maximum write speed from the strategy table, so the display of lower write speeds is not accurate.
