The DX-20A4PU performed very well when reading single layer DVD-ROM's. In our tests it started reading at 6.55x and reached a maximum transfer speed of 16.25x.Looking at the other scores, you can see that the drive's seek times were also quite good.
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.

Lite-On'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 5.93x and accelerates, reaching 12x at the 2.8GB 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 DX-20A4PU didn't slow down very much when reading single layer DVD videos. It started out at about 6.65x and reached a maximum read speed of 16.09x. Lite-On's new drive was also fairly quick when reading dual layer discs. By looking at the screenshot below, you can see that the drive's transfer speeds peaked at about 12x.
To see how well the DX-20A4PU 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.
