I have a dish model 311 and i have it hooked up to my dvd/vcr player, and it's been working fine for the past 2 years i could record and watch my shows, but now when i try to record it just records a blue screen and i can't watch television unless my vcr is turned off, both channels for the tv and the vcr are set to 3, and i've tried checking the options for any changes and no luck, any help? or ideas on what might've happened? Thanks.
