I have a LG H55N, and I can not get it to read DVD-Rs. Normal DVD’s work fine however. I tried updating the firmware from 1.3 to 1.5, but there was no improvement.
Upon inserting a DVD-R with data on it, it tells you it is a blank DVD, with 0 bytes used, 0 bytes free.
There was another thread about this, but their problem was due to Alchohol or PowerISO, and I don’t have any programs like that on this computer.
I’ve removed the drive and used it in other computers with the same results, so the problem is in the drive itself.
