Having a bit of a snafu. Trying to connect an H24-100 to a Sanyo SDTV. The Directv box has no S-Video, only AV and HDMI. I have tried the AV hookup but am getting no signal - just a 'snow' screen. The TV has only a few settings and it is set to receive signal from Cable. I believe this should be working, but no go so far ?? This worked b/4 when it was a Directv SD box and connected to the TV Coax.
