More likely you've got some Windows background operation that's interrupting things.
Pyros are great for capturing video!
Make sure Windows Indexing is turned off.
Run a complete virus scan with Malware Bytes.
Beyond that, it's hard to say without knowing your operating system, computer specs, what other software you have installed, etc.
well,here's an update:
reloaded XP and PREL...no change.
installed the FIREWIRE card,it's cable,the PYRO and the new VCR on my main computer (the one I'm on now, the one I do my audio work on) everything works fine! (so I know the hardware is ok)
reinstalled everything back to my "video" computer, same thing!
BTW: I DID turn off indexing Steve, must be something else in the background.
anyway,that thing where the little icon in SYSTRAY disappears seems to be normal 'cause both computers do it and this one worked ok.
looks like it might be a hardware problem. the motherboard may have "bit the dust"! besides having one !@#$%^ of a time getting PCI devices installed after I reloaded XP,everything seems to get better (but not COMPLETELY better) the further down the PCI bus I put the FIREWIRE card.. the more I think about it, I'm realizing that I really have had pci problems right from when I put this comp. together. I just ignored 'em because things seemed to work. looks like I'll be buying another mb pretty soon.
MB problems can be really hard to troubleshoot... my 3+ year old ASUS has a back panel eSata port, which I recently discovered does NOT work unless you make a specific BIOS setting at the time you first setup your computer (can't remember details, something about hard drive configuration) so now I am NOT going to wipe my drives and change that BIOS setting and reinstall everything just to use an exernal eSata drive... I will just live with the S.L.O.W speed of a USB2 external
