Interference from Firewire??

[alhenderson]

Morning All,

For the last couple of weeks I have been trying to burn a DVD of stuff on my camcorder, and have been frustrated by 'blocky' output from the camcorder. When I capture, I get horizontal lines of blocks coming and going. See image below:




I don't see this when I play back the tape through the TV. I have tried another camcorder and it is fine, and I have also cleaned the heads on mine.
However, last night I noticed that I could see the blockiness on the camcorder screen when I had the firewire cable plugged in to the camcorder, which would seem to indicate some kind of interference between the firewire cable/card and the camcorder. I have a Canon MV940, the other one which didn't suffer from the problem was a Panasonic.

As I see it, 3 options: my cable is not very good (its a bog standard one, nothing special), the firewire card itself has a problem, my camcorder has a problem. Since one camcorder is OK, I'm inclined to think its my camcorder, but I guess it could be that mine is more sensitive to some kind of interference than the other one.

I see you can get shielded firewire cables - are these any different to normal ones? I've always been a little bit sceptical about cables and connectors that are gold plated and this that and the other..

Has anyone come across anything similar?

Thanks,
Al.

What does that mean, and what can I do about it?

Thanks,
