DVD rip slow compared to previous- why?

[sledhead406]

Ive searched around and cannot find anything like what I have, sorry if it has come up before.

I had a disk go down in my server that held a decent amount of DVD and Bluray rips, no big deal as I can do them over again. When I ripped the originals, I was getting very fast rates with DVD and reasonable rates with BluRay. Unfortunately I cannot remember the rates but I would guess around 8-12X for DVD. They only took about 5 minutes each. Now I have not tried a BR again (yet), but DVD disks are topping out at about 2X and take a good 45 minutes to rip. I can transcode two DVDs with Handbrake much quicker than I can rip one!

I rip from a Pioneer BDR 209 onto a Seagate 1TB HDD, then I use Handbrake to convert to MP4 and send it on over to the server when all done.

CPU load is never above about 1% while doing the rip. But I never even really hear the disk drive spin up like I did before.

The only changes to the workstation since last ripping DVDs was a hard drive swap- but the DVDs are going onto the same HDD as before, so I doubt that is the issue.

I did just try a firmware update on the optical drive to 1.34 and there is no difference. I also tried changing the read buffer rate from "auto" to "1024mb" as it is the highest setting available, but no difference there either.

So why would identical DVDs rip so quick before and now be incredibly slow with (what I consider) irrelevant hardware changes? Something to do with riplock (have not heard of this until researching just now)? If so, why would it be quick before but not now?

In case any is relevant:
AMD FX 6300
16G RAM
990 chipset on Gigabyte board
Boot/OS/programs on Samsung SSD
Rips to Seagate 1TB 7200rpm
Bluray/DVD drive is Pioneer BDR 209DBK

Pioneer has a Windows utility to disable "quiet mode" on their drives, which will make them rip faster. You'll have to search for it, though, if you don't have the original DVD that came with the drive.

An update: Turns out disabling my anti-virus software took it back up to normal function.

Im guessing that an auto update of the AV software changed something along the line.

If anyone else has this problem and notices that your default media player does not automatically open the disk (if set to autoplay*) where it did previously, it may be a hint that the AV software is the culprit.
