Will this work?

The following is a description of how I intend to hookup my system. The system consists of:

Scientific Atlanta 8300 DVR
Onkyo TX-SR600 AV Receiver
Toshiba 36HF73 TV
Memorex MVD2042 DVD Player

The scheme essentially keeps the video out of the receiver and uses the receiver for
only the audio. Any comments would be appreciated.

The VIDEO connections:

1. 75 ohm cable to DVR ANT IN.

2. 75 ohm cable from DVR ANT OUT to TV ANT 1.
The purpose for doing this, in case all else fails, the TV can be used by itself.

3. S-Video cable from DVR S-VIDEO OUT to TV VIDEO 1 S-VIDEO IN.
This takes the video directly to the TV without any switching going on in the receiver.
Don't know why any switching would be required.

4. Component cable set from the DVD COMPONENT VIDEO OUT to TV COLOR STREAM
HD-1 IN.
This gives a higher quality video signal when using the DVD only. The DVR doesn't have
a component output and the receiver can't upgrade/convert any of its video inputs to a
component signal. But, both the TV and DVD are each so equipped.

The AUDIO connection:

5. Coax cable from DVR DIGITAL AUDIO OUT to a Digital to Optical Converter DIGITAL IN.

6. Optical cable from the Converter OPTICAL OUT to Receiver DIGITAL INPUT OPTICAL 1.
The converter is required because the receiver has only one digital audio coaxial input
but two digital audio optical inputs and there are two digital audio sources, the DVR and
DVD. Neither have optical outputs.

7. Another approach to 5&6 above would br to use a digital coax A-B switch. 7 sounds
better but then you have to remember to operate the switch, ha.

If you could upgrade to an 8300HD SA box you could go HDMI out to DVI in on your TV with an adapter cable and gain an optical audio out as well. Sooo - have you thought about getting the HD package?

No it wont work in one small area,

If you want to use TV with cable box run a splitter from wall wire and go one into the DVR box and one straight to TV......some DVR's allow use of basic cable without box being powered up via a setting in box menu. The reason I say run splitter from wall direct into TV is because you can still do what you want without DVR use but if your DVR dies or has some malfunction it wont affect watching tv my way but your way it just may be an issue.
Other than that and advice that you run best wire possible to your display at first glance everything else is fine, cheers

That's provided his cable signal is strong enough to take a split (-7.5db) - been my 'sperience that analog cable signals are usually already grainy without being split. If donbart doesn't want to get an HD box now - I'd just pass it through until the box dies... ... then upgrade to the HD box to take advantage of the HD signal handling capability or that particular TV.
