XHA1s and FS H200 Green Screen oddity
 

I've posted this in another thread, but so far no response. I'm hoping someone sees this here and can shed some light on my problem.

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.
