Liquidmagic - worker said it wasn't broken until the SB02, but I was having problems with it reading DVD-R discs with SB01. I think if you hold on a little longer there might be a new firmware soon that fixes this.

mike18xx - Nope mines from Compusa, it was sold under the Mad Dog Multimedia Brand. I owned one of their older drives, and I was impressed with it. When it started acting "odd" i went looking for a replacement. The MegaSTOR 18X triple format Internal drive seemed like a good deal... until I started burning discs. I then got a Memorex 16x drive, and its slow and loud, then the MegaSTOR went on sale so I figured I would try again... I'm not giving up entirely, but this is really bad.

Oh and I finally had a few minutes to sit, so I burned a DVD-R video disc on my trusty Sony... put it in the SD182D and imagine that... it can't see the disc.
So I think the SB04 firmware is still half right, it now can make a DVD-R that anything else can read, but it has no clue what to do with a DVD-R when you ask it to read it.

Of course the easy solution with Samsung Tech support is ask them to burn a DVD-R, and then try to read it on the drive. If its the SB04 firmware its gonna fail. Hard for them to not understand the issue then. No need to go into mm and measurements until you get someone who has a clue.
