Best Way to Import and Edit MP4 Files with Premiere Pro CC

Problems when import MP4 files to Premiere Pro CC

Although Premiere Pro CC has officially claimed its native support for MP4 files, however, people still encounter various problems when loading MP4 files into Premiere Pro CC as below:

CC2015.1 Update - now there's no audio from MP4 clips
I upgraded to the latest CC apps from 2015 to 2015.1 and opened up a project I'm working on which consists of MP4 footage grabbed from YT. Everything was just fine when I edited these clips in CC2015, but since upgrading to 2015.1 I'm getting no audio from them, in fact Prem Pro is adamant that there's no audio on the clips! I've tried starting a new project and importing the clips again but still there's no audio. However, in CC2014 I can import the clips and they work with audio no problem at all. GSpot is reporting the clips as MPEG-4 AAC LC.

MP4 files freezing in Premiere Pro CC
I have a previously exported game clip that I've made, its only about 20 seconds long. When I imported it back into premiere at a later date in order to implement it into a longer video, it freezes halfway through, then unfreezes after 5 seconds or so. The audio continues to play. No matter how many times I import it, the freezing is always in the same time frame.
