Hi Mark,
Thanks for getting back to me. There is no tbc or proc amp in the line. The betacam is hooked directly via s-video cable to the dvd recorder. On almost all tapes that originated on betasp, there is no problem at all. But it seems like betacams that had been originally created from a 3/4 or VHS source have the strange signal artifact at the tippy-top of the frame.
Oh yeah, and one more important thing…
This artifact never appears on a standard TV when played back from the DVD-R in a standard DVD player, but the artifact becomes present when viewing in a computer or miniDV camcorder.
What’d ya thinK?
