Hi, I have a AV32R, DVD32FLR (both with latest software) and just bought a CDT20R-T2L. they are all connected through T2L. unfortunately, when I now play a DVD through the FLR the sound is muted (red light on AV32R). I believe I've set everything correctly in the menu's, including key assignments (to the best of my knowledge!). Regarding the rear of the AV32R, The CD is connected to the digital input (phono plug) marked CD. The DVD is plugged into the digital input (phono plug) marked DVD. Regarding the DVD32FLR, the cable comes out of the socket marked digital output 1. Regarding the CDT20R T2L I'm using the digital phono output. I've used True Colours Industries Adder digital interconnects which have been working fine. i wondered anyone else had had a problem like this and help shed some light. thanks. Steve.
