Connect HD51 to modulator

[edmundf]

Hi, did you ever get this working? I have an 3.5mm jack cable with 3 phonos on the other end - red and white for audio, yellow for composite video that I've plugged in the HD51 AV port. I want to drive an old Slingbox via composite video and I'm getting stereo audio but no video - I've tried to connect to the similar AV ports on my TV and same story. I'm running OpenATV and the only video options I have are for HDMI or SCART - even though the HD51 doesn't have a SCART socket. I've tried this setting and choosing CVBS but still no video output! Any idea what settings need to be used to enable the video out?

Hi I just bought a Muntant HD51, works well but I need ANALOG audio out for my high quality audio amplifier.
What kind of signal is coming from those red and white phonos ( cinch ) plugs?
I get NO sound from it!
