I have my DSR920 hooked up to the loop out of my Openbox S10. When I am watching channels on horizontal sit gets reception. However if I am tuning Vertical the DSR920 shuts the signal off on my S10. I am using a dmx242 lnb feeding it into a 4x1 diseqc switch. Is there an easy way to get past this? Why won't it work on vertical? I am currently unable to run a separate coax into this receiver. If anyone can share some setup ideas it would be great.
