RT2000 & Betacam problem

[Jhon Lyon]

Hello, sorry for my english.
I have a problem when recording of the RT2000 to Betacam, the video signal REC without colors(black & white). But, I can capture from the Betacam fine.
I have actually a Sony UVW-1800P.
I tried capture in PAL DV 4:2:0, and I tried
before record to U-matic and after to Betacam and its OK, but loss quality.
TBC needed?.

Somewhere down the chain of Q & As I seem to recall someone turning up the gain on the signal going into their Rainbow Runner to combat their Black & White capture probs. Could be your Betacam is expecting a signal with a lil' more umph.
