Hey Bob,
Here’s what I got from the JVC website for the BR50HD :
Versatile analog connections :
In addition to IEEE 1394 input/output, the BR-HD50 is equipped with analog component (BNC) output connectors for HD and SD. Y/C input/output connectors (SD mode) and composite input/output (BNC) connectors (SD mode) are also available.
So maybe it does support analog HD output.
