Everything is working fine and hooked up correctly according to the user's manual. The problem i am having is when I change a channel to a HD channel it loses signal for a good 5 minutes and then gives me an error. I can only then get back a broadcast. I'm thinking it loses the signal because when I'm on an HD channel it's looking for that 129 satellite that the DISH500 i'm using doesn't pick up. I've spent a good portion the the day looking for a real manual for this ViP722 that actually tells me how to use it but to no avail. The user's guide is worthless in my opinion. I'd like to turn off all HD programming instead of going through hundreds of channels to lock all the HD channels... I could also be wrong about my approach to this problem. Please help me?... and anyone know how to get my hands on a actual technicians guide to a ViP722?
