DC10plus With Partitioned HDD?

I've recently purchased a Pinnacle DC10plus as my introduction to non-linear editing.
I am using a 13Gb HDD,partitioned 4/9.I am using the 9Gbs for video capture and play back.During capture everything seems to work fine at any disk speed up to 5500kb/sec,with no frame drop.However playback after rendering is jerky and this is particularly noticable in the audio.I presume that the problem is to do with the read rate of the disk,but this is indicated as 8771Kb/sec using the DC10s own test program.Am I expecting too much(the problem is much reduced at VHS quality).Would I get an improvement in performance if I had a seperate boot drive,or must I buy a faster capture drive.Unfortunatly money is tight so any suggestions would me much appreciated.
I have tried the usual things such as disableing write behind and setting read ahead as zero,neither action seemed to have any effect.Disableing virtual memory had only unfortunate effects.
As an aside, has anyone had any luck with Pinnacle own(25p/min.)help line?

Kind Regards

It's just occured to me,as i'm unable to run my system without virtual memory could it be a ram problem.I currently have 64mb.I should also add that it is not possible to tick on DMA enable,but I havn't a clue what this means.

Ah, I've found the two articles written by Bob Crabtree on this very subject.I now have DMA enabled in the Bios and the box ticked in windows.Although the gain in speed didn't seem much it has transformed the system,I can now capture and play back at full quality of the capture card without dropping a frame.Thanks Bob!
However this has resulted in another annoying problem.When playing back 'smart sound' from the CD Rom,before rendering,it keeps dropping sections of the music.After rendering it's fine.Again I am unable to tick in the DMA enable box in windows,for the CD Rom,although it appears to be enabled in the Bios.I get the statement CD ROM UDMA33 in the opening box on startup(the one you can stop by putting a non boot floppy in).As you can probably tell,I'm not a computer whiz so a point in the right direction would be appreciated.

Kind Regards

Clive, I don't have an answer.

While you are waiting to see if anyone else does, you might care to check out the official support site accessible on Pinnacle's US website.

Start off at http://www.pinnaclesys.com/default, and navigate your way to the DC10 plus support pages.

Thanks Bob, I did as you suggested.There a found a link to an article by Phillip Allwood entitled Tuning your PC for Video.
Following the advice in this article has certainly improved things.
I'm sure the 'old hands' are familiar with this info but for anyone new it can be found at; http://www.intop.net/~jamessw/pcsettings.htm
Now to experiment importing wildtracks into DC10plus!
Thanks again Bob

Kind Regards
