Has anyone checked the audio quality that goes to the headphone jacks/on-board speaker? I was wondering if it could be used for production audio output, and used in conjunction with the HD component video out. Thanks.

Don't know but why not use the RCA L-R outputs? Connector?

Ken, where in the world do you have RCA audio output connectors on your HD100??? There is no such thing.

Terry, I do use the line out (3.5 mm stereo jack) and it works fine.

My bad. Sorry about that, Ervin. You are absolutely correct. I was busy and my mind thought about a mini/rca "Y" connector and it all came out wrong.
