Post subject:  video quality
Every day I record some OTA local channels and then I transfer the files to my PC, where I edit them and save them. I have been saving them as .m2ts but that seems to take up too much space. About 1 gig for a 5 minute video. So I have been experimenting saving them as just a .ts file, and it seems to look the same but only using about 1/4 of the space. So I was wondering if you guys could help me out by downloading these two videos and telling me if you see a difference or maybe I'm just being too picky. The first video is a .m2ts that takes up more space, and the second one is the .ts for less space.
