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.
