My problem is this I have a the following setup and cannot capture digital video without dropping 30-50% of frames

1ghz CPU intel
80gb hard drive 7200 rpm
512 mb ram
firewire card Texus Instruments?
Sony DCR TRV120E Digital VCR

With either Premiere or MGI Videowave
Ive tried closing down everything else running in the background except for a couple of things.

Please help

DMA off for the harddrive? Only thing I can think of.

do you have a seperate partion for the captures? I have a seperate drive(s) for my firewire and I drop 1 to 2 frames for every 68000 frames or so of capture, using a SIIG firewire board ( texas instruments chipset ), 512 mb ram and a intel 933 p3 proc ( 815 solano chipset ). So it's similiar to yours. My capture drives are ata 100 7200 rpm 150 gb ( 2 - 76gb drives in raid0 fashion ) on a hipoint controller. Captures are made thru Adobe Premeire and Ulead Media Studio v 5.0.

I would agree with tommy, sounds like you dont have DMA enabled for your hard drive

Hi,
Do you have the indexing service disabled. Right click on c: or any other drives if using 2000 or XP and go to properties and disable indexing.

Also disable i.e. uninstall any virus killer software or Norton optimising utils you might have installed. Virus killers tend to cause a very high performance hit on capture machine.

Is you capture machine a lean set-up with plenty of empty space on your capture drive and defragmented. Or is it used for other purposes and therefore as other things installed which might hamper it.
