DLA problems with Plextor PX-712

[Ian]

I'm hoping RPedigo can shed some light on this...

I'm trying to packet write to a 4x DVD-RW disc using a Plextor PX-712SA and DLA 4.90. Unfortunately, the performance is terrible. It takes more than an hour to write the data when it should take less than 13 minutes.

I had this problem with v4.60 and it is still there with 4.90. Any chance Sonic will improve support for drives from non-OEM customers like Plextor?

Ian,

I probably already know the answer, but just to be sure... do you have the newest firmware for your drive?

[Ian]

Of course.

I've had problems with DLA and Plextor drives since the 708A. With that drive, DLA wouldn't even format the disc.

As long as I'm talking about problematic drives, DLA also has issues with the Pioneer 108/A08. Here too, it takes forever to write the data to DVD-RW discs. I'm not sure if this is a problem with DRT-DM or what.

Also, does the same problem occur with non-rewritable discs?

You COULD try clean installing DLA...

Yeah, this was with a clean install of DLA. Lemme put it simply.. there are some issues with DLA. Even with 4.90. I'm very surprised that the software engineers don't test with drives from Plextor, Pioneer, etc. since they're some of the more popular manufacturers.

No, I haven't tried it with write once discs. I don't usually test with those.

[RPedigo]

Ian,

I am aware that some burners have issues with DLA, and we're expanding the amount of supported burners with each release. Let me know if the problem persists with the write-once media. I'm sure our testing will branch off into non-OEM vendors, but you have to understand that they need to be one of our priorities. If a vendor who has a deal to package our software comes out with a new burner, it may take precedence over another, as we need to ensure that our software that the company is buying is compatible with their product.

Quality Assurance is definately testing new drives every day, but we've got many more months before every burner is tested and certified or not.

I don't mean to rag on you. These are issues that have been bothering me for some time. If QA needs some help, let me know. As it is, I find myself beta testing half of the drives companies send us. Testing the latest build of DLA with them would not be a problem.

too bad they don't show their appreciation more
