Since you mention Blu-ray I moved the thread to the Blu-ray sub forum.
Let me know if it is not a Blu-ray disc.

Download VSO inspecter a free program and run a scan on the disc to check for error.

Just wondering .. were you just copy to HD or compressing to BD25?

Maybe 1st disc was under 25GB and 2nd needs compressing down to BD25..

**LarryM04** · 05-16-2010, 01:43 PM

Yes, its BluRay, thought I'd set that. Thanks for moving.

The first disk was BD25, this one is 33G compressing down to BD25. But its now been running over 10 and a half hours and is 69% complete. Surely the compression to go from 33G to 25G imposes that bad a deal. Yes this is going to HD for later burning.

The best practices for what you are try to do is to rip full disc or main movie to hard drive first as BD-50 setting, and then compress down from the hard drive to fit your disc. Doing it this way saves time and wear and tear on your drive, as it is not spinning for hours accessing your drive for information.
Also make sure you are using the latest beta
Hope this helps

First ensured the drive had the latest firmware, 1.08. Then downloaded VSO Inspector. I assume the tab of interest is "Scan".

I put the 2012 disk in and started it up. Its rather boring, so I checked back periodically.

For about the first 20 or so minutes, it was showing a read speed bouncing between 2.4 and 4.2 - mostly hovering in the 3x range. No "Problems" no "Errors" The plextor is a 12x drive.

I came back just now and the read speed has dropped to 0.2x (!!!) Still no problems, still no errors.

So what the heck can be going on to make the read speed so bad?

I am on the 7.0.5.8B version, tho DVDFab seems to be the victim here.

This is what VOS showed when I stopped it (it still had 17 hours to go):

Larry, as CBR mentioned...rip the movie as BD50 to your hard drive first!

Then take the BD50 file and compress to BD25.

Also, when compressing...the specs of your PC come into play...if you've got a crappy processor, low RAM, etc its going to take a loooooong time!

(which is why you should rip BD50 first...that way your disc drive won't be running for hours on end!)

**LarryM04** · 05-16-2010, 04:15 PM

I think I was writing as you were.

I don't have a killer box, but its 4g with Win-7 64, dual core proc. It compresses DVDs in a reasonable time.

Its the read speed. When I start DVDFab the read speed shows 2.x m/s, but then declines to the 0.x range. Same that VOS Inspector did.

Why would my read speed be so bad?

**crackinhedz** · 05-16-2010, 04:18 PM

try ripping to BD50 first...no compression.

then let us know how the read speed went? could just be a bad disc? (even if no visible damage?)

**DharmaBummed69** · 05-16-2010, 04:56 PM

I have the Core 2 Duo E7500 2.93GHz Oc'ed to 3.02GHz and I get between.50mb and .75 on the slow/high quality setting so I think this is normal for dual core processors although I was getting .99-1.0MB steady when I was using a GeForce 8500GT with CUDA. That changed with my new video card HIS Radeon HD 5770. I think DVDFab plays better with Nvidia at the moment. Just finished up An Education compressing from 30GB to 22.4GB. It took 11h 53m to complete and looks good. I'm going to try one of the 40GB+ discs next so I expect it to take longer. Also the time to completion isn't always accurate at the beginning. When I first started it was up around the 20+ hour mark but once it got past the extras and previews into the main movie the time to complete became accurate. So what first was a 20+hour job really was only less than 12 hours. What I'd like to see is max compression for previews, PCGs and extras so we can have minimum commpression on the movie as most of the previews looked way better than they had to be(15-20MB a sec). At least better than I think they have to be as I find having to manually skip 6-8 previews annoying to begin with. I do what crackinhedz suggests. Rip it to hard drive with BD50 then use the ISO to compress to BD25. Also want to report that now you can choose the ISO as the source instead of having to mount the ISO on the virtual drive with 7.0.5.8b. At least for me on 7.0.5.5 I'd choose the ISO and it would load and scan it but when I'd push Start nothing would happen so I had to mount it and choose the virtual drive as the source. Glad to be able to lose an extra step.

**DharmaBummed69** · 05-16-2010, 05:46 PM

An edit to my above post. Results were for fast/normal not slow/high. I guess the new beta reverted the settings when installed as when I checked it was on fast/normal and it had been on slow/high quality previoulsy.

The read speed - as shown in VOS Inspector started off decent (2.x to 4.x), then dropped out to 0.2x. VOS Inspector is just reading, not doing anything with the data

I'm trying VOS Inspector on the other disk, the one that only took 16 minutes to rip.

**LarryM04** · 05-16-2010, 06:27 PM

What's the difference between VOS's "scan" and "file" reads?

When it scanned, 100% good, reasonable read times. Then it started the file test, and again read speed is 0.2x - and this is the disk that ripped in 16 minutes.

What's going on???

**LarryM04** · 05-16-2010, 07:39 PM

Here's the rest of the VOS output

2010-05-16 14:04:12 Info File test complete
2010-05-16 14:04:12 Info Average read speed: 0.26x
2010-05-16 14:04:12 Info Maximum read speed: 0.37x

2010-05-16 14:04:12 Info 92 files scanned
2010-05-16 13:20:47 Info File Test started

So now I'm more confused... average read time, 0.26x -but- it read the disk in 44 minutes. ???

**LarryM04** · 05-16-2010, 08:46 PM

Took a chance, set the rip output to BD50 and... it was done fairly quick.

Is the compression that bad for BluRay? I've done lots and lots of DVDs, none of them took hours and hour to process.

Running the compression from HD - it currently says its going to take 5 hours. Really? 5 hours?
