The GH22LP20 was fairly quick when reading single layer DVD-ROM's. In our tests it started reading at 6.57x and reached a maximum transfer speed of 16.05x.Unfortunately, its seek times were not as low as some of the other drives.
Nero CD Speed v4.7.7.7 - DVD-R, DVD-RW and DVD-RAM:
First, we'll look at the drive's DVD-R and DVD-RW reading performance. For this I made copies of our DVD-ROM test disc using some general use 4x DVD-R and 2x DVD-RW media from Verbatim and then ran our usual DVD read tests with CD Speed. For the DVD-RAM tests, media from Maxell was used. The results are below.

LG's new drive has a maximum transfer speed of 12x when reading DVD-RAM discs. By looking at the screenshot you can see that it starts reading at 5.92x and accelerates, reaching 12x at the 2.7GB mark.

Next we'll look at the drive's DVD+R and DVD+RW reading performance. For this I made a copy of our DVD-ROM test disc using some 4x DVD+R and 2.4x DVD+RW media from Verbatim. I then ran our usual DVD read tests with CD Speed. The results are below.

The GH22LP20 didn't do as well as the other drives when reading DVD videos. In our tests, it reached a maximum speed of only 6x when reading both single and dual layer discs.
To see how well the GH22LP20 worked as a DVD player, I watched a few scenes from Transformers: The Movie and Star Wars: The Phantom Menace using Nero Showtime. The drive had no problems playing back these movies with either program and was fairly quiet.
