Yes, still a little buggy, but it's normal for an Alpha release.
I think it's on right way, to be a success....
Here are my contibute:
1. HD channels picture flicks
2. When zap between 4K channels it crash, and must restart manually
3. "Mouse Button" on wetek remote, does notink and make lose remote control. Must be pressed again. It was good if could do the job and make mouse apear on screen as on WebOS
4. Missing Online Plugins like Softcams.
