I'm wondering if this is a known issue. Fairly often when watching a live program on my just installed Hopper With Sling, it gets all flakey and I'm unable to rewind. If I try to rewind, it just freezes and gets stuck. If I can get it to rewind a bit, when you try to play, it stutters and the audio cuts out. This also occurs if I try to watch a recorded show from the DVR. Recorded shows won't allow me to fast forward either. I have stumbled onto a work around that kind of works though. When the above happens, I swap to the other tuner, change that channel to clear the buffer, then come back to what I was watching on the other tuner, and I am able to rewind again. I can also then watch a recorded program and fast forward as needed. Of course a complete reboot fixes it too. But it happens at least once just about every day, so it's quite annoying. Anyone else ever seen this?
