Plextor PX-708A 8X write quality and strategy

vbimport

#1

For this small test I’ll use all different types of 8X capable 4X discs and use the create data disc function in CD-Speed. I’ll scan the discs with two different Lite-On drives so we could look at the produced results :wink:

Plextor PX-708A, F/W 1.01, 4,38Gb.

Notice the big quality difference between ritek and arita discs which is identified as the same discs!!
Notice how easy it’s to see where the speed shifts is on the quality scans.

Seems like plextor have to improve write quality or that we have to wait for the real 8X discs.


#2

For this followup I’ll use the exact same discs and drive…but just write at 4X using nero 6.0.0.11.

Notice the big difference between the LTC-48161H and LTD-165H scans…

Write quality is still not as good as from the Pioneer 106/A06 (memorex dual-x).

Nice, that’s the best proof of what I’ve been
repeating about C1/C2/PI/PO errors not being
on the disc, and it will hopefully encourage
scan freaks to be more cautious when
comparing plots from different drives.

Thanks for your comment spath. Please comment more on posts like this as then I may be able to learn something from a way more technical person than me. :wink:

Yes, it seems like Lite-On DVD-writers, DVD-ROMs and Combo drives do all report PI/PO errors different…and the worst thing is…there is no system on which discs which drives like…it depends on writespeed, writer and disc brand… :confused:

This is a huge problem for our new DVD media test forum as different people have different drives and this makes comparing results difficult :frowning:

" To compare or not to compare ? " - that’s the question !

Let’s all have the same type of drive and media - this will ease the comparison.

So you say that we should limit the dvd media testforum to scans from one drivetype only?

Nope we will not do that…

Oh boy, I don’t think you quite understood my ironic tone.

Well, you’d rather explain then what exactly you meant in your statment “This is a huge problem for our new DVD media test forum as different people have different drives and this makes comparing results difficult” ?

I mean, what a problem ? People are supposed to have different drives and different media.
Otherwise what’s the purpose with being involved in the process of gathering and evaluating all the different data coming from different sources ?
So, aren’t the problems you’re “facing” what you have been expected ?

I seem to be running into similar problem. I wanted to do an extensive DVD±R test for which I have two identical computers. One is fitted with the Plextor 708 (and Lite-On 166), the other with the Sony DRU-510 (and also Lite-On 166).

Testing the exact same media I get very different results. The Plextor drive creates reproducable graphs - between 3 DVDs I burnt, the graph only deviates with a small margin.

The Sony however, produces completely different graphs each time. None of the DVDs “look alike”.

I’m at a loss on how to continue. Why are the results so damn different…
