Those of you who know me will know that I am not technical at all! I have a 3.24 GB movie which I just downloaded from Youtube (in 1920 x 1080 definition). I wish to then place this on my USB > to my blu ray player > watch movie, and most importantly, Id like it to be high quality and the quality to not drop hugely. However, I realised my player does not play MP4 files. So now I am stuck with a MP4 file which I need transferred to another format which my player can read (Im assuming .avi or DVD format), and I also have a Mac. Are there any specific Mac tools which can help me convert this easily, without losing the quality? The main reason why I downloaded this from Youtube is because the quality was amazing.
