I am having trouble connecting my DVD1 to BV5.  The dvds play fine when connected using S-video cable but the screen flutters when the two are connected using a 21 pin cable.  I bought this cable at a local hardware store because I was reluctant to buy it from the local B&O dealer who asked for US 80 dollars.  Could this be the problem?  Are B&O 21 pin cables specially designed for B&O products?  Or is there another reason for this?

I've had the same problem a few years back; the first scart/21 pin cable did not do anything at all, the second one I tried gave a shivering image on my avant and the third one did the job, the difference was the price.......:-) because the cheapies were not completely 21 pin wired.
