Any more ideas for printing to tape?

I've think that I've tried all of the suggestions posted throughout this forum for correcting my "Print to Tape" problem. To summarize:

Running Win98SE on a 910MHz Athalon, 128 MB, on a VIA chipset motherboard. I've installed latest "4-in-1 Drivers" from VIA. I've also installed the Microsoft patch from support.microsoft.com/support/kb/ articles /Q252/9/58.ASP that is supposed to fix the problem regarding high-bandwidth IEEE 1394 OHCI controllers. DMA (actually UltraDMA) is enabled to my Maxtor 30GB 7200RPM hard disk.

I can capture video to a NTSC-DV AVI file flawlessly. The video runs perfectly in full screen using Windows Media Player. When I "Print to Tape" or "Preview on Camera" I get only portions of each frame, with random irregular rectangular blocks missing. Also audio dropouts. While there is some video, it is completely unacceptable for playback. (Note that I do all of this after a fresh boot with no other apps running.)

Most of the posts in this forum have pointed to bandwidth problems through the 1394. But I don't understand why I can capture but can't print? Shouldn't that be the same bandwidth in both directions? Ant thoughts or explainations?

Are there any freeware applications for printing to DV tape so that I could verify that this isn't a problem with Sonic Foundry Video Capture?

Does anyone have any other good ideas?

Thanks tremendously,

Matt

The behavior you get could be an irq problem-try giving the 1394 card and the vga card their own, unique irqs. If that still doesn't help, try moving your 1394 card to another pci slot.

You are very close to a solution I think, but right now there's a system problem and data throughput is getting choked at some point.

I had a similar problem with my VIA chip motherboard. Like you, I could capture from the DV camera to the computer flawlessly, but printing back to the DV camera wasn't working right. I determined that I did not have a bandwidth problems through the 1394 by setting up a ram disk on my computer and copying an avi file to it. Printing from the ram disk to the camera worked fine. Then I tried copying the same file to a freshly defraged partition on a hard drive. It would not print correctly to the camera when DMA was turned on. I turned off DMA and got a perfect transfer from the hard drive to the camera.

Are you sending back the exact same file you just captured, or are you rendering it, first, into another .avi file. I just learned, through trial by fire, that the NTSC DV render setting needs to have the "interleave every frame" box checked for it to print back rendered video correctly to my camera, as I had the same problem of blocks missing and such. Try this, and see what happens. You may also check the "Losing Fade-Ins on Print to Tape" topic, as there's more on my troubles and solutions...

Good Luck,
Scott

Thanks for all the suggestions, I'm trying them all. But now I have a whole new problem in that I've got the dreaded "yellow exclamation point" by my firewire card in the device manager. Happened after I installed the latest 4-in-1 VIA drivers. Stupid Windows. I'm getting dangerously close to a re-format.
