David,

A low cost method of outputing all of your video sources to all of your TV's is:

a) connect all of your video sorces to your A/V receiver
b) buy a single channel stereo modulator
c) connect the VCR2 record outs to the inputs of the modulator
d) use the record out selector on the A/V receiver to choose which video source to output to the modulator

The major drawback of this arrangement is that you will only be able to view two video sources simultaneously, one in the theater and one throughout the rest of the home. However, with only two of you in the house it may suffice or at least will reduce the cost of all of the modulation channels in the interum.
