I bought a new BC2 for my BV8. Picture is very nice even though it is just a scart connection.
I thought about picking up a used one, however as you said there are permutations and I wanted the later one.
One the early versions, it is somewhat annoying how you operate that thing. I.e. you have to press the "go" key twice to start dvd playback.
There are a few things that annoy me right now with my setup, mildly, not enough that I contacted the dealer yet.
For one, and this is the biggest, when I start CD playback on the BC2 it takes a few seconds until the speaker turn on, so I always miss the 1st few seconds of the CD. Software glitch.
When you use the wheel to change volume, i think if you go quickly up and down it mutes, I haven't really figure out how that works.
Lastly, I think if you activate DVD through the remote, I think it blocks out the pad on the BC2. If activate the DVD straight from BC2 that doesnt happen.
The later 2 things dont really bother me, that it fires up the speakers a few seconds to late does though and I will take that up with my dealer at some point. Is just software issues I think.
Otherwise I am super happy with that combination, haven't regretted a second that I made that move.
Cheers
JK
