If your has multiple inputs, then, I would simply connect the vcr to one of those inputs using the composite cables (red, white and yellow), and the cable box on a separate input as well. If your cable box has composite outputs or S-Video (even better), then I would hook up the cable box to your tv using those connections. Preferable S-Video if your cable box has the outputs, but if it doesn't, then use the composite outputs.
Hope this helps
I have an older model VCR, it's probably 7 years old or so. My current connection to my TV and digital cable box is as follows:
Coaxial cable from wall to digital cable box.
Coaxial cable from digital cable box to VCR.
RF Cable from VCR to TV (yeah, old school...)
As it is currently set up, everything works perfectly, but the picture on my TV is a little grainy. I've taken the VCR out of the loop (ie, running the coaxial from the wall to the digital box, then from the digital box to the TV) and the picture is improved. BUT, I can't use the VCR.
Does anyone have any recomendations on how I can include my VCR in the wiring, but improve the TV picture quality? My VCR does have inputs/outputs for the 3 prong red/yellow/white cable. I know that a DVR is the best option, but I'm not looking to do that at this point.
Thanks for your help!
