This may be a bit off topic, but if someone could take a few secs to help me, I'd appreciate it. After getting my firewire card working, it appears that it is not recieving data from my camcorder. I have a panasonic pvdv800. What is the proper procedure for getting video to come out the mini dv port on the camera? Just putting the camera in VCR mode, and hitting play? dvgrab loads successfully and sits waiting for data, but never gets any. thanks in advance mark to...@de... |

For me, dvgrab does this on first run. Then press ctrl-c, try again, and it works. Did you try again? ----- Original Message ----- From: "Mark" <to...@de...> To: <lin...@li...> Sent: Friday, November 17, 2000 3:48 AM Subject: Re: Linux1394-user digest, Vol 1 #15 - 4 msgs > This may be a bit off topic, but if someone could take a few secs to > help me, I'd appreciate it. > > After getting my firewire card working, it appears that it is not > recieving data from my camcorder.

Yeah, i think i found the problem, the DV cord doesnt seem to have been made correctly. Thanks mark Dan Dennedy wrote: > For me, dvgrab does this on first run.
