Re: Lost frames, or what else?

Dear Dan,

thanks for your kind answer. So you think it could be a problem with the
firewire card. I have another one, so I could try that instead. I must
also say that the 6pin plug of the Canopus is not working anymore except
for the power. I must use the other 4pin plug for capturing, and the
6pin one for powering on the device. I strongly hope it's not damaged, I
bought it just a couple of months ago and it was quite expensive, at
least for me!

Indeed, I couldn't say whether the two thing are linked some how.

Best regards.
