0.8x speed burning BD-RE??? Help!

[icicle22]

I finally took the plunge and bought a Pioneer BDR-202 and I am not thrilled yet!

It came with a TDK BD-R and BD-RE.

I have only tired the BD-RE which is clearly marked as 2x.

I cannot get anywhere near 2x speed when burning. In fact the Roxio software reports the media is capable of 2x speed but it actually burns it at 0.8x speed, making a 25GB disk take about 2 hours! I expected 45 minutes and I thought that was long. What is going on?

I have tried it in 2 PCs so far using the sata connection.

The first PC is a DFI motherboard based on the Intel 965 chipset with an intel sata/raid controller. There are 4 sata drive setup in RAID, and the burner is the 5th.

The 2nd PC is an older P4 board with sata on board. On this PC there are no other device attached to the sata controller at all.

To add to this mystery, I had previously tried the SOny BRU-100a in an external firewire case and had horrible performance on a 2x SOny BD-RE. The sony is an IDE drive also. Even when I put it into the PC internally it still wrote at less than 1x. What is up with this?

Is there no way to get a Blu-Ray burner to write at the 2x rated speed to BD-RE media? I need to test my Blu-ray movies before I burn the final bd-r (haven't even tested this yet to see how fast/slow it will be). 2 hours to watch and preview is too long.

Any help would be appreciated.

By the way, I have been building my own custon workstations for my video editing company for 10 years, so I know my way around computer pretty well.

Thanks.

Well I will reply to myself with even more gloom and doom.

I have now officially tired this burner on 5 different PCs, with 3 different software packages.

Cyberlink BD solution
Roxio
Adobe Encore Cs3

The drive never write faster than 0.82x.

I am using the TDK BD-RE media that came with the drive. I have not used a BD-R yet as I don't want to waste it.

Since this happens on every PC I have tried it on, is has to be one of 2 things.

1. A defective drive
2. Bad media. (although I have used bot Sony BD-RE and TDK BD-RE and same results.)

Anybody having any luck with an BD-RE at all? I had to wait 2 hours and 5 minutes for a full 25BG burn last night. That is just too long.

Thanks.

Just a thought: Try having your Roxio DVDit Pro HD write a bluray .iso image and use your burning software to write the result. I always burn this way and seem to get about 2X on single layer BD-R or RE (Sony, or Imation Inkjet printable). I timed a 45 gig backup (MyPictures!) to a Panasonic dual layer BD-RE/50 and it took just over three hours. I have a Sony BWU-100a.
P.S. Sony just announced their own 4X drive

Another thought: I once did "drag and drop" onto the BluRay drive and it took forever. In that mode I think it opened the directory, wrote the file and closed the directory....with each file. That is the mode you want to avoid. The .iso burn or backup with Cyberlink "create Data Blu-Ray" avoids this doing it is a single "project".

Look for new firmware on the web site. Even a minor upgrade might make a difference.

Beyond that, contact technical support or send it back.

This is actually normal. The software is telling your drive to verify the data, which makes it look like you're writing at only 0.8x. With some software, you can disable this feature. Unfortunately, I don't think CyberLink's BD solution has this option.

This situation is easy to reproduce with CD Speed. Burn a disc with the streaming option disabled and you'll see the drive writing at 0.8x. Enable it and the drive will write at 2x.

ya just disable it and time hpow long it takes then divide the time by the data burnt

icicle22,

It may be a bad drive, but also may be SATA controller issue.

I have LiteOn LH-2B1S SATA BD burner. My motherboard is Gigabyte GA-965P-S3. It has 4 SATA controllers controlled by Intel ICH8 chipset, and another 2 SATA controllers controlled by some Gigabyte SATA chip.

When I connected LiteOn to the SATA port, it was Gigabyte chipset as I found out later, I had a lot of problems burning BD-RE disks at 2x with Nero and ImgBurn. Then I found on some forums that people were having problems with different SATA controllers, and that Intel ICH8 chipset was the best.

I reconnected drive to Intel ICH8 chipset, and I am a happy camper.
I can burn 23GB of data on BD-RE disk at sustained 2x speed with ImgBurn in 43 minutes. Nere also burns at 2x.

Not all SATA controlers are made equal.

I hope this can help.

I agree but this isn't an SATA issue.
