I'm having several issues with my sling adapter connected to a 722. First, if anything is recording on the tuner that the sling adapter connect to, it will only show that show and in live mode only. I am unable to watch any of my pre-recorded shows. Secondly, I get a strobing effect usually during commercials (i.e., pc display blinks in quick succession). It seems that it occurs when there is a lot of white background. Third, I can't seem to get connected unless I minimize or switch to another tab when the pc is connecting to the sling adapter. I am using firefox to access dishonline.com but have also tried ie 9 with the same results.
