The DH-4O1S performed fairly well when reading single layer DVD-ROM's. In our tests it started reading at 5.10x and reached a maximum transfer speed of 12.28x. Looking at the other scores, you can see that the drive's seek times were also quite good.
CD Speed v4.7.7.7 - DVD-R and DVD-RW:
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 disk using some general use 8x DVD-R and 2x DVD-RW media from Verbatim and then ran our usual DVD read tests with CD Speed. The results are below.

The DH-4O1S had no problems reading DVD-R, DVD-RW and DVD-R DL media. In our tests, the drive read DVD-R discs at 12x, and both DVD-RW and DVD-R DL media at 8x.
CD Speed v4.7.7.7 - DVD+R and DVD+RW:
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 disk using some 8x 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 DH-4O1S performance was very similar to what we saw with DVD-R, DVD-RW and DVD-R DL media. The drive read DVD+R discs at 12x and both DVD+RW and DVD+R DL media at 8x.
CD Speed v4.7.7.7 - DVD-Video:
For these tests I am using the US version of Transformers: The Movie on DVD. The disc is over 4GB and single sided.

The DH-4O1S didn't slow down very much when reading single layer DVD videos. It started out at about 5.05x and reached a maximum read speed of 12.16x. 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 8x.
To see how well Lite-On's new drive worked as a DVD player, I watched a few scenes from Transformers: The Movie and Star Wars: The Phantom Menace using the bundled version of PowerDVD. The DH-4O1S had no problems playing back either movie and was fairly quiet.
