Hello. I just got a new DVD player and I need some help connecting it.
I already had my TV connected to a Dish Network DVR receiver. My TV is older and only has one cable connection on the back of it, which the Dish Network receiver is connected to.
When I got my DVD player, I was under the impression that I could easily hook the DVD player directly to the audio/video jacks on the back of the Dish Network receiver. I tried this my connecting the audio/video out from the DVD player into the audio/video in on the Dish Network receiver. I thought that I could use the TV/Video button on the Dish Network remote to switch from TV to DVD mode. This did not work at all. No audio or video from DVD player.
I also tried the same with the S-Video connections on the back of the DVD player and Dish Network receiver.
Can I hook my DVD player directly to my Dish Network receiver? What am I doing wrong? Please help.
Thank you!

Oftentimes some of the capabilities of these cable or sat receivers are disabled. You can try calling your service provider and asking.

Otherwise, you could buy a switcher. You can connect 2-4 components to the switcher and then connect it's output to the TV. If you truly have an old TV with only a screw-type RF cable connector and not even the red/white/yellow plugs for audio/video input, you should also buy an RF modulator. Ideally, buy something that combines these two items, such as the Magnavox M61151, which is less then $29 at Amazon

Also, you could buy a new TV. It sounds like you use it a lot, so it would be worthwhile. You can put the old one in your bedroom or office.
