Is running simultaneous dvd9 to dvd5 compressions ok?

[flip69]

DVD2one allows many copies of the program to be opened simultaneously but I was wondering if I run 4 copies of the program and compress 4 movies into 4 destination folders will the resultant quality of each be the same as if I ran each one at a time. Since it takes about a hour for a complete movie I thought I would let 4 or 5 copies of the program run all night and in the morning all the compressions will be done in the final VIDEO_TS folders. This seems to work but I cannot tell if I am losing some quality or there is some other reason not to do this.

Thanks

You`ll just lose encoding time per session running but should make it up for the number you have going but the encode quality will remain the same unless you over do it and run out of processing power.

the quality won't fluctuate no matter what, it will produce what you asked for, or it won't produce anything and will freeze up (not likely no matter how slow you PC is.)

in some cases doing two at once will actually take a bit longer than doing two consecutively due to time slicing (os job handling) - if my suspicions are correct and I am applying my OS CompSci education properly.

drewson is pretty much correct. Also remember that the faster encoders such as DVD2One and DVD Shrink are using up pretty much ALL of your IDE bus bandwidth. Running 2 of them at once will NOT be any faster, but neither will the end results suffer.

This is DIGITAL, people. Not analogue.

as above, it will take longer doing them all together than doing each one indivdually

but what is beyond me is why you need to run that many at once?????????

do you plan on doing this every day? as that's over 100 backups a month. I know it probably won't happen but if you do this all the time, don't be surprised if by chance your HD goes pop. Doing this day in day out means the heads will be whizzing all over the place continuously for hours at a time

If you don't do it all the time then just do them one at a time

why the hurry people? Think of the Cadbury's caramel adverts

if you have the original just back it up as you need them and you will soon backup your collection
