I have just purchased a Panasonic TX28dt2. It has 2 scart sockets labelled AV1 & AV2. If I connect my Panasonic NVHD650 to AV2 the videos will only play back in B&W. If I connect the VCR to AV1 playback is fine but I cannot then tape digital channels whilst watching another channel in analogue which Panasonic claim should be possible. Has anyone else suffered this problem? or have I got a faulty set? The suppliers state that the set is fine.
