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

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.

PI levels are high near the end of the disc but are within specification. PIF error levels are low and our read-back test is perfect; a good result.

The PI error levels are quite high throughout the burn and PIF levels are fairly constant throughout the burn, but all well within specification. The read-back test is perfect and the result is good.

PI errors are rising towards the end of the disc, but are well within specification. PIF errors values are low, but fairly constant throughout the disc. The result is good.
DVD-ReWritable media:
We used the same testing
procedures as we did for DVD-R media.
Our obtained results can be seen

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.
Head on to next page and read about DVD+R DL compatibility and write quality...

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





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?
