Problem with dvdshrink

[malleus]

i have used dvdshrink for some time now but i went to shrink a dvd today an it was only shrinking at 345kb/s usually ots working at 1800kb/s. i uninstalled the program an reinstalled it an it is still running so slow i have a 40 hour wait time for it to finish. anyone know what to do?

Something else on your computer may be using all your cpu cycles (virus perhaps), or your hd is full/fragmented and the program is having trouble finding space to read/write.

I would also check your DVD drive and see if it is reading slow. It may have defaulted to PIO mode:

To check DMA/PIO mode within Windows:

Control Panel>System>Hardware>Device Manager>IDE ATA/ATAPI controllers.

From there, right click on one of the channels and choose 'Properties>Advanced Settings'. All drives should be DMA mode. The 'Current Transfer Mode' for Hard drives is usually DMA 4-6 and DVD burners DMA 2-4, DVD ROMs usually DMA 2. If you see any in PIO mode, that can slow things down.

Changing them back may be easy or complicated. First see if you can change them in that window. If not, I usually uninstall the channel the drive is on and let the OS reinstall it. This will usually take a reboot and it should correct the DMA settings. If not, see if they can be changed manually. This will not damage any files on the computer.

But you would also notice this with burning or any other data access to or from the drive.

And welcome to our forums.

Rip the disc to your HDD first, then shrink. DMA/PIO is the most likely cause, although there were reports a while back that Shrink would eventually slow down if you didn't periodically empty out the old analysis files. They are somewhere under Documents and Settings/YourAccount. I have never seen this behaviour myself, but then I don't use Shrink a lot.

guns1inger, I had heard the same thing about Shrinks analysis files. But looking further, those files seem to be about 150 -200Kbs each, so I always doubted they would cause any problems. I only have a guess about PIO/DMA modes, but I thought it might be worth checking.
