DVD R/RW Writing performance
 

DVD-R media compatibility and write quality:


In these tests we will be using a Lite-On SHW-16H5S with firmware LS0T along with K-Probe to measure the disc quality. We will also be using the NEC ND-3540A with firmware 1.03 along with CD-Speed for our read-back tests. 

For these DVD writing tests, the Plextor PX-755A was set to the following.

         Power Rec on
         Auto Strategy on
         All media had been stored in the Auto Strategy database prior to writing the disc.

PI errors are just within specification, and a cluster of PIF errors near the end of the disc are worrying. The read-back test is perfect. The result is ok, but not what we expected from this very good quality media.

The Plextor PX-755A has handled the Verbatim DVD-RW media well. A very good result.

To sum it up: Overall, the write quality is generally good/very good on DVD-R and DVD-RW media.

I own this drive. Overall very satisfied. One issue up till now: I burned a CDR Audio disc with Nero (7.x latest version), by dragging some MP3 files to the audio disc. Although the disc is readable, it has a lot of hickups in the audio, which are also shown in the mm:ss indicator. Tried two burning speeds (48x and 4x, does not want to burn slower speeds) on Taiyo Yuden media that always worked in previous burners.
I am undecided if this is related to the drive or to the software. Need to do more coas^H^H^H^Htesting for that :)
Could be Nero, version 7 has been known to be having some problems producing glitch free audio CDs from mp3s. Unsure whether the latest version (7.0.8.2) still suffers from this or not.
Hi,

I've got this Plextor PX-755A DVD drive as well now. But I've got some problems.
CD's and DVD's read very well, no probs there. CD's also burn well. But when I try to burn DVD's the burning software locks up and the drive doesn't want to give my DVD back.

I searched the whole net for this problem but didn't find any solution for this problem.

Specs:
Intel P4 1.8 GHz
2*515 DDR-SDRAM
MSI MS-6547 main board
win XP Pro SP2
Burn programs: Nero 7 / Plextools

When I try to burn the burning begins well untill the amber light of the 755A starts to flash. Then the burn % meter stops. After 2 minutes the amber light stops flashing and turns green.
Now IE7 is stuck, burn program is stuck, DVD is stuck. The only way to get my pc running again is Ctrl+alt+del and stopping the burn program. IE7 still doesn't do a thing and my DVD is still stuck. Pressing the start button for a moment shuts down my pc and then I can start my pc again.

Anyone got some pointers for me?
I'm the owner of a Plextor PX-755A drive and I'm overall very satisfied of it. Burning and reading goes perfect except for one part, the drive doesn't erase most of my DVD-RWs and DVD+RWs correctly and makes them useless. I'm using Nero 7 with the default drive firmware and tried with Sony DVD+RW and Philips DVD+RW discs, most of both were erased incorrectly. I'm currently installing Nero 8 and looking for a firmware upgrade and hope to get this problem resolved.
