I have a Hopper w/ Sling and 1 Joey, and the problem is isolated to the Joey. I can change the Format on the Joey on any HD channels between the various Zooms/Stretch/Grey Bars, but on SD channels it is stuck on Grey Bars and will not change, no matter what I do with the remote. Am I missing something, or does this seem like a glitch? Like I stated above, this happens ONLY with the Joey, the Hopper will change between formats on SD channels with problems. Any suggestions to cure my ignorance would be appreciated.
