DESPERATE: Drop frames with DV Now lite

I recently installed DV Now lite on my new system, running both W2000 and Me, and I cannot capture more than 2 or 3 seconds before a frame is lost and the capture is aborted. The number of frames is variable, but it doesn't support more than half a minut or less.

My system is as follows:
Asus A7A266 motherboard, With alimagik 1 chipset
128 mb of PC133 RAM
XP 1600+ Processor
Winfast S320II Riva TNT 2 Ultra Graphic card
Sound Blaster Live! Sound card
3COM ADSL USB MODEM
Primary IDE - IBM UDMA 100 DT309030 7200RPM
SECONDARY MASTER sanyo 4x cdrom
secondary slave Ricoh MP906030 dvd / cdr COMBO

There are no conflicts with the cards, but IRQ 9 is shared with Graphics, USB, sound and DV card in W2000. With ME nothing is shared.

I've tried to force it on the motherboard, but windows 2000 still share irq 9. Card works well (tried on other system), SO AS hard drive, since I've tried it on this hard drive on another system with the same card. I've tried to shut off CD DRIVES, SOUND CARD, ETC, but nothing.

I've tried also with Seagate drives, but there's the same problem.
That problem is both on W2000 and Wme. Fast does not capture, but plays well. I've even output to tape.

I'm completely out of clue, and technical support cannot help me. I'm desperate. Please, if somebody can help me, please drop me a line. Thanks.

check your Hard drive(s).
the problem must come from them.
maybe you ve got many hard drives so that you had to combine 2 drives on the same IDE port.
So if you ve got an old drive(5400rpm) and a recent one(7200rpm) on the same IDE port, both disks will slow down, so you won t be able do capture DV on the fly.

You should make some tests with a Hard drive benchmark tool like Sysoft sandra and check the speed of your drives.

After that, try to isolate your fastest drive on an IDE port alone, and test again.
You ll notice the difference.

YOur problem is truly a Hard drive problem.

Hi and thanks for your reply,

I don't think the problem came from the harddisks. Both disk were used to capture form DV Lite perfectly on other systems(pentium 3 with Iwill motherboard) and another athlon with asus A7V motherboard. First system used 128 mn of ram and second used 512 of DDR.

I've tried them in both ide channels, in all combinations and still there's no result.

Are your disks declared in DMA mode ???
Check your BIOS.

On new motherboards drives are usually set to auto detect UDMA settings, but it is one thing to check for sure. Also check that UDMA has not been disabled in the BIOS for the IDE controllers themselves - it should be enabled by default - but again worth a check to make sure.

My guess is that your problem lie's with the OS themselves and the driver in use for the UDMA(ATA) Disk controllers. Install the motherboard manufacturers driver for best results to ensure DMA is being used. If however you have to use the generic Microsoft driver that comes with Win2K and ME then check that DMA has been enabled for the disk drive you wish to use (by default it is NOT) find this in device manager>disk drives>properties>settings tab.
