Still issues with playing movies

I raised my rating from -1 to 2, because some movie "channels" play better than others. HBO, no problem. Reg channels, no problem, Starz.....Well theres the problem; movies played by them (that Ive noticed so far) seem to randomly quit and then do not restart and throw an error code regularly. But like now I just checked the move that stopped on Starz and everything is working again. What the heck?

General problems:
- Sporadic error with no playback, seems to be from specific channels; for example it will suddenly stop playing movie on Starz and will not resume but no problem playing a movie on HBO
- Videos freeze with audio still playing (They did seem to fix that one for the most part.)
- Badly designed gui & cant bookmark shows to watch, and locating anything is a mess (they fixed this too)
- Streaming is supper slow (this seems fixed too)
- Really only 3 devices allowed? Step into the 21st century and join the rest of us; most families have more than 3 mobile devices (which makes no sense since its a premium service). For large families I cant imagine how they could use this app.

With all the other options out there I still pay a HUGE premium to Comcast for their crappy penny pinching services. I mean, wow I pay over a hundred bucks (nearly two) a month and they cant compete with another company (like Netflix or Amazon) who I pay ten or twenty dollars to? Wheres Comcast focus?.

Grant it, they have improved the app considerably from where it was. But with movies randomly stoping, refusing to play or whatever interrupts a movie Im watching, and it happens on a regular basis, well I still cant give it more than 2 stars. Playing movies is the main point of the app and the whole business for Xfinity (thats the service I pay them for every month), and if it fails 30% of the time (just an off the cuff estimate, may be smaller/larger but seems close) then its really not great at its main function.
