What up with RCA DVD Recorder/VCR with Digital Tuner, DRC8335? - dvd recorder vcr with digital tuner great machine

I do not understand this RCA DVD Recorder / VCR with Digital Tuner, DRC8335? I have a put and do not function well. The TV tuner is to select the channel search and it is not a video / audio, DVD, but work hand in the game. I DishDVR and you put him in and still does not work. Who has (this DishDVR production and use, for example, 522 or 625) have a job, I wonder how? I did everything I could imagine. Do you have an answer for me, for I am ready to return.
