Hello,
I have no problem with playback on either device, as long as the other device is not being used. However, whenever I use the Genie Mini, it causes playback on the HR34 to skip and stall. It's so bad, I have given up watching TV on the mini whenever the other TV is in use. Playback is not affected on the TV with the mini. I haven't had the time to call support yet, and am hoping that there is a quick fix here. Thanks.
