I have a Sager laptop that I use extensively for on-the-road travel editing. I've had trouble with interruptions during capture (firewire). Sometimes, I can get an entire tape finsihed without problems - often I'll keep having my capture stopped, while the camcorder keeps right on going. Here are some of the conditions I usually operate under:
Antivirus and internet - Off
No other programs running in the background
Unused tapes, prior to videoing
Tried using different camcorders, with no difference
Tried "Tape" command, no difference
Any constructive assistance will be greatly appreciated!!
