VIA = dropped frames on export? end of rope...

I'm at the end of my rope. I've read every resource I could scour through, tried at least 60 hours of fiddling, to no avail. I have a good 20 min of editing done, and I'm unable to get it back to my camera without dropping frames/blue screen-ing (it happens randomly, but frequently -- gaurunteed with each attempt of timeline-export). Here is an in-depth description of the horrible troubles I hope some wonderful guru graces me with a solution to:

System:
900 Mhz Athlon Thunderbird
Windows XP on an Asus A7V (Via KT133) Bios rev. 1004
384 MB PC-100 ram
30 GB IBM Deskstar 40GXP (ATA 100, 7200 rpm) (holds only OS and programs)
60 GB Maxtor (ATA 100, 7200 rpm) (Newly added -- all the footage is now here)
FMI (CompUSA brand) FireWire card
Creative SBLive! Sound card
PS/2 intelli-eye mouse (I moved this from USB port, and completely disable USB support: still no dice)
AGP Creative Graphics Blaster (Geforce 2 GTS on the latest detonator drivers)
Sony DCR-TRV730 (It's both digital and analog camera -- right now, all the footage im working with is on hi8 tapes, if this makes a difference).

My system meets the Premiere requirements, so I'd love to get this working. You may notice that my BIOS ver. is pretty old: I started out with XP and ACPI, a completely fresh system, just the OS, Premiere, and the above hardware. I got capturing to work pretty well (though most of the footage pieces are not that long, and I got the occasional bluescreen). With an updated (6.02) Premiere, playback on the desktop looks great, but I disable that while exporting to the camera (of course -- that's one of the first things I tried in hopes of fixing this). Everytime I'd try to write to the tape, I'd get dropped frames/ blue screening. So I read and researched about ACPI and IRQ sharing (nearly all my devices were on 9). And after many hours of twiddling, I have a clean system with XP just installed, stripped bare of everything but the essential. No irq's are shared, my Promise IDE controller (irq 10), firewire card (9), soundcard (5), and video card (11) and everything else are each on their own irq's. I really thought IRQ sharing was the culprit, but, alas, still the same problem. In fact, for a while it was worse, since I flashed my BIOS to the latest revision during my reinstall of non-irq-shared XP and ended up with an export that dropped more frames than successfully written! I couldn't believe it and thought I had broken the card, returned it for another -- same problem. On a whim, I finally downgraded my BIOS back to the original, and it was back to semi-crap (hence the low ver.). I wonder if it's my motherboard/VIA chipset altogether -- is it just DV inaccessible? Anyone else out there with an A7V and success? I've made sure every driver i could update was updated and MS certified, defragged my hard drive, configured Premiere as best I could, banged my head against the power supply, tried multiple PCI slots, different firwire cables, screamed very loud, rendered it all to a giant avi and tried just exporting that (these are a few of the things I tried that I can remember now...) -- nothing is working to fix this. Is it my firewire card itself? I think I'll pay some nice restocking fees and try a "better" (well, certified, at least) card just to be let down one last time before I burry my computer for good. It plays back wonderfully and realibly (un-rendered) on the desktop... but I can't get the d*mn thing onto my camera, then vhs... So, that's all I can muster right now. Anyone out there, I'm begging you -- save all my effort.

The problem is with the VIA chipset(PCI Latency) on the A7V I had problems with DV capture, and managed to resolve them by using Georges PCI latency patch(try searching for it on Google) I still have an issue with exporting to tape in premiere but i can export succesfully in Ulead mediastudio.
 
hallo there

I have exactly the same problem (but with an athlon 1gz system); thankd for the info , I will try the patch. Loopinfinitum, if you're thre, did it work for you . .?

cheers,

You may want to also consider getting some more ram. Video eats up an insane amount of ram. I have 1GB, and at times I wish I had more. Hope this gives you some help.
 
Not sure why this thread is finally getting some action, maybe it's the Christmas Season... Anyway, I tried George's PCI patch a long time ago and it did nothing for me. Nothing I did worked except scrapping Premiere and using Sonic Foundry Vegas Video to do all my video exporting. I still edit in Premiere (ugh) export to a huge .avi, then use vv5 to write thru the firewire -- much more reliable, and actually got thru all the footage without dropping a frame.

In conclusion, buy Mac.
