First of all you need to make sure that the Audio and Video Source that you're using is compatible
Besides that, you can check the following link:
Thanks for taking the time to answer. I'm hoping that an update to the Slingplayer software or SOLO firmware will give me back the features that I had with the Slingbox AV.
I'm wishing that I would have stuck with the older Slingbox AV - I'm not getting any benefits and losing the DVR button and DVR item in the guide is a huge step backwards. The AV had the features touted by Slingmedia and I'm getting no better picture from the SOLO - every time I attempt to use the HQ picture, I can no longer control my Tivo from the iPhone or iPad. Also, I mainly use the player via 3G on the bus and the HQ stream is unwatchable, even if the remote control worked.
For me moving from the AV to the SOLO has been a disaster and the lack of support from Slingmedia just adds insult to injury.
