I just bought what I thought was a lg4163b, but on the casing at the back it reads as a 4161b. Is there any difference between the 2 drives. Did I get ripped off. Any advice would be appreciated
The 4163 supports DVD-RAM. The 4161 does not. Even if you do not use this format, I would consider it a rip-off.
And LG doesn't provide firmware updates for 4161 because it isn't meant to be directly sold to consumers.
