CUDA slowing down encoding?

[Kannkor]

I have 2 computers I use for ripping/burning movies. Originally I used my gaming PC, which is a quad core 2.8ghz proc with a decent vid card (GEForce 9800 GT). I could encode (with compression to fit on a BD-R) in a few hours.

Tie-ing up my gaming rig I wasn't very fond of, nor having to copy the files.. so I built a little server. It has an i7 3ghz proc, with a $10 video card (literally). Some times it takes 14+ hours to encode (with compression). I do see that it says CUDA GPU acce is enabled.. Because it's such a cheap video card is this hindering my performance?

Example of the movie I'm doing right now.
Green mile (GREEN_MILE_THE).
Original BD -> Full disc ISO (no compression) to disc.
ISO -> to BD-R (compression from 27gb to 22gb to fit)

Total Elapsed time: 16:03:51
0.45 MB/s, Percent: 84.62%, Task Time Elapsed 16:17:35, Task Time Left: 03:08:44

Thoughts/suggestions?

What is the make and model of the video card? Have you tried setting DVDFab to all Software and not using CUDA at all? Correct driver for the video card?

NVidia GEForce 8400 GS.

No, I keep forgetting to turn CUDA off, but I never remember after a 13-18 hour encode session.

Just wondering if this could be hurting me or not. When this is done (1 more hour it says...) I'll try another with CUDA off to see if it remains this slow or not.

I turned off CUDA, hit okay, it said it needed to restart. Press okay. I hit okay, it restarted DVDFab. I started it... "CUDA GPU acce.. enabled.."

It started off going fast (10mb/s).. but it's quickly decreasing... down to 2.8mb in under 2mins.. I bet if I let it go long enough it'll take the same amount of time as above.

Went back in, apparently I only changed the encode option.. changed the decode option to software instead of CUDA.

I don't get the CUDA GPU enabled anymore. So far, not sure I'd say there is any difference...

Guess that changes my question now.. any ideas/suggestions on why some take so long (seems to be any that need to be compressed)?

Looking at task manager and it's using 90%+ CPU over all cores (i7 3ghz), so it's processing at pretty much cap.

Only thing I have installed is DVDFab and PS3MediaServer. Any thoughts?

13-18 hours encoding time!?! Wow! Consider the amount of time, energy and money you're wasting.

I say you bite the bullet and utilize your gaming rig to bring those encodes back down, shaving off 10-15 hours.

You might get faster overall time and will get less wear on your optical drive if you write the output to your hard drive if it needs compression, then use that as a Source in Blu-ray Copy to compress it to whatever size you use. Some of the disc-to-disc difference could be the type of stream on the discs--MPEG-2,VC-1, AVC etc.

I do write it to my HDD first.
My process is always:
Original BD -> Full disc ISO (BD50) to HDD.

Full disc ISO from HDD -> to BD-R(25).

I do believe it has a lot to do with the streams on the disc, I did another one right after the green mile, with the same computer, same settings (didn't even close down dvdfab) etc. I even already had the ISO, and it took < 3 hours. It needed compression also. I may to check, load the ISO into my gaming rig and see how it does with speed. If CUDA can make THAT much of a difference, I guess I consider a video card for my fileserver, or.. not worry about the time it takes. That computer serves two purposes, to share files, and to rip and burn movies. So if it takes 18 hours for the odd disc.. it's not really hurting me. Other than when the wife wants to watch it and I tell her she can't use the original and has to wait...

First your timming reminds me of when I use to back up using a dual core. When I got my quad core everything went down. to and hour and a half max. And now with my 6 core an hour is the longiest so far. So in short do you have any other dvd/blu-ray burning and or decrypting programs open?
