Not only is Jetflicks the BEST kept secret with the fastest updates to hundreds of shows... but NOW in HD!! Finally the shows look not just OK on the FIRE.. .but now they are AWESOME!
The regular video format (called m3G) always looked sharp and crisp on my Android phones and current iPhone4. It was when it was scaled up to the FIRE's larger screen that it started to look "sub-standard." The new format, called mHD, appears to be 4 times as crisp and clean. Funny thing is, I do NOT see the difference on my iPhone screen from m3G to mHD, but when I hit that AirPlay button and send the videos to my AppleTV... WOW.. there is the difference on a 42" plasma.
From what I can tell, each day the NEW episodes are released in both HD and the earlier 3G version. Most currently airing shows go back 3-5 episodes in HD quality as of today. Jetflicks support reported that they are currently going back to every show in the entire libraries and producing the HD versions.
Bottom line is that it is certainly the most used App on my 3 devices.
