FS H200 Green Screen oddity
 

My Canon XHA1s recently stopped playing back through its tape transport, so I thought I'd give a DTE a try. I purchased a second-hand FS H200 which has been working well.

I recently added a green screen studio and have found that my recorded footage is very sporadic. It will record for a minute or so just fine but then I have blips where I am missing about a second of footage. The problem recurs at irregular intervals, sometimes after about 10 seconds, sometimes after about one second. But the net result is that I can't shoot green screen. If I shoot in another environment the footage seems to be just fine, but when I sheet green screen I get this weird dropping of footage.

Has anyone ever experienced anything similar? I can't even figure out how to trouble shoot this problem.
