Videos recorded in landscape mode

I recorded a really important event yesterday, holding my camera horizontally with the top of the phone to the left, and I then transferred it to my PC and a flash drive. When I played it on my computer it is sideways. I tried to edit with Window Live Movie Maker but it won't play the MP4 format videos. Does anyone know why this happens, and what I can do to fix this? I know I am not supposed to be shooting videos vertically, they look terrible.
Any help would be very much appreciated!

Why does my camera play videos in portrait when I record in landscape?

I'm on the SM-N910V Retail, or the Verizon Galaxy Note 4 Retail. I'm on Lollipop 5.0.1. When I use the camera app to take a video, I record in Landscape (phone tilted on its side), but when I transfer my video to my Windows 10 PC (same problem on Windows 7 prior to upgrade), my video plays in Portrait, and not only that, the video is tilted 90 degrees. It's annoying. Back in Windows 7, IIRC, playing the video in Quicktime seemed to fix the problem, however Quicktime doesn't seem to play in Windows 10. If I Open With Quicktime, I see the first frame of the file and it appears frozen.

How can I fix this?

[Q] Nova launcher landscape padding

For a long time I was loving nova just for what it was for me - "A perfect launcher". But now I have a problem I never had before. Landscape padding. I was always using my phone in landscape and nova was ok with it. But now I am unable to get the widget to the absolute bottom / top of the screen. Even though I have paddings set to none the is simply a little line where I just can't get.
If anyone would be able to solve my problem I would be grateful.
