DVD Read Speed is Sloooooowwwwwwwwwww....

I built a new system a few months ago and the DVD-RW has been driving me crazy because of slow read speeds. My system configuration is as follows:

E8400@3.0GHz
Gigabyte GA-X38-DS4 Mobo
2GB DDR2-800 Crucial Ballistix
BFG 8800GTS G92
2x Seagate Barracuda 7200.11 500GB 32MB Cache Raid 0 Config
Corsair 520w PSU
Asus DRW-2014L1T SATA DVD Burner <=========
Windows XP Pro x32
LG 245WP Monitor
LIAN LI PC-V1200Bplus II

According to Nero Discspeed the read speed for this drive is only 1.6x! It takes an absurdly long time to rip CD's, install games, etc. In addition it takes a long time (>20sec) to recognize a cd/dvd.

I've tried enabling DMA, but there are no IDE Channels listed in device manager (all of my optical and HDD are connected via sata). I took an old IDE dvd-burner from one of my other computers and installed it in this system, and the read speeds weren't much better (~3x). Evidently the JMicron JBB36X controller manages IDE, and the IDE drive was listed as a SCSI device. When I checked the registry I found that DMA is enabled for all SCSI devices, so are there any other reasons why DVD drives are running so slowly on my system?

Could it be a driver issue? I installed the ICH9R drivers when installing windows, and the rest of my drivers are up to date. Onboard IDE is enabled in BIOS, but there are no IDE devices listed. I have heard that ICH9R has a problem with optical drives, so should I just suck it up and accept that this drive is gonna run slow?

Please Help! This has been driving me crazy!

Thanks for the reply, gord1!
I ran Nero Drivespeed and it only detected read speeds up to 8x, which is the minimum DVD read speed according to the manufacturer. I set it to read at 8x, but according to discspeed it still runs at ~1.6x no matter what DVD format I use.
There are two other odd things I've noticed about the drive. The first is that Discspeed always mentions "hybrid disc type" whenever I run a speed test, and secondly, If I delete the DVD device from the device manager and reboot Windows, it never seems to reinstall the driver correctly. After Windows detects the hardware, it never gives me a notice saying the device is ready to use, which is peculiar because I've never had that happen before and yet the DVD drive still works and is visible in My Computer.

Hey they still have the same problem with the nigabyte motherboards with the P45 and the GBBX36 Jmicron chip which is IDE and raid and doesn't seem to have a setting that will make it right in windows, I was burning disks on my ASUS board for some time with no problems at all, then I went to the nigabyte motherboad and have had nothing but problems from day one, not only is it slower than my ASUS Striker II formula but the Jmicron problem is still there, and all I did is go to Jmicron and get an updated driver and it helped, I can't believe that thease lazy ass;s at nigabyte couldn't even just add the driver update at their website, I guess they were to busy laughing on the way to the bank, needless to say as soon as I can I am selling this board to the first sucker I can find and getting my ASUS back in, I was gonna try the ATI Backfire but now I am not intrested with all teh problems I am having with this EP45-UD3P I am going back to what works, ASUS and Nvidia!! you can have the rest, this is just my 2cents worrh I know is late but better late than never ... peace out
