Does DVD Shrink 3.2 use multiple cores?

[mrfatboy]

I thought DVD Shrink 3.2 uses multiple cores. I loaded Speedfan to watch core usage and then encoded a dvd with DVD shrink. Speedfan reported only that Core 0 was being loaded up 100%.

What gives?

I'm not sure if it does or not. I thought that development was halted on DVDShrink. You may want to check out Handbrake, not sure if the Windows version has come along any since I last used it, but it may be worth a shot. Handbrake works like a charm on OS X and is multithreaded, so I would assume that the Windows version is as well.

The anonymous creator of DVD shrink disappeared sometime around 2004. Most popular theories include an assassination perpetrated by the MPAA or that Nero hired him. Needless to say, I really doubt that the program was made with dual cores in mind.

Yes it does. DVD Shrink 3.2 uses multiple cores. I haven't tried it on a quad core but I know it uses both cores on the duals.

The author was hired by Ahead to write Nero's "Recode" software which, not surprisingly, looks an awful lot like DVD Shrink.

I'm still not convinced that it does. Speedfan is only showing 1 core being used 100%. Is there an option to use multiple cores?

open two instances and encode two dvds at once!
thats theonly way.

ok, then I was right then. DVD Shrink only uses 1 core per instance. I was hoping to burn 1 DVD in half the time

Uhhhh, I'm not sure what your burn speed is but I'm absolutely positive its much slower than one core of your CPU.

DVD shrink just encodes. It doesn't burn DVDs.

Isn't DVD Shrink I/O limited anyway?

 

[mrfatboy]

It should be able use both cores to encode. It's just basic number crunching. However, since it was written awhile ago I guess the programmer didn't consider multiple core. Hence my original question.

Not unless you've got an extremely slow hard disk or optical drive.

Technically everything a computer does is just number crunching but that doesn't say anything about the real work it's doing. A/V encoding is hard to parallelize because later blocks depend on the previous blocks to already be compressed to determine what the full frame will look/sound like.

I was just responding.

DVD Shrink does use at least 2 cores. I just tested it on my AMD X2 system (in Vista 32bit). Process manager showed that it spawned 19 threads, and pegged both cores at 100%.

I don't have a quad core to test on, but it most certainly does utilize both cores on a dual core CPU.

hm fired it up and apparently it does.
i haven't used it in a long time, i use clonedvd 2 because it can deal with menus

Just to chime in for confirmation, DVD shrink does use 4 cores. However, I start hitting I/O limitations after 3 cores. I'm running a RAID 0 array and I cap out at about ~75% net utilization, give or take 5% on a QX6700 @ 3.4 GHz. It does tend to hover around 3 cores net, but no other processes are taking up CPU and it does peak out at 81% net utilization and dip to 71% at times. Regardless, I seem to be hitting I/O limitations before I peg all 4 cores, so it does let me do some multitasking since my video processing RAID is separate from my OS/Application drive
