First let me apologize if this question has been answered before. I have searched for Video Format threads and Handbrake threads, read them, tried things out, but I'm still stuck. I just received my phone today, so I'm still a noob when it comes to all of this, so please forgive my ignorance. I just downloaded my digital copies of UP and WALL-E onto my Mac with the intention of putting them on my Evo to watch. I can watch them fine through itunes in .m4v format. Through research, I have found that m4v's are basically the same as mp4's and that the Evo should be able to playback m4v files. However, when I transfer to my SD card (I made a "Videos" folder in my SD card) the video shows up in the native Video player, but I get an error saying it's unable to play. Additionally, I have tried downloading Real Player and mVideoPlayer and those too can see the file, but can not play it back. So I decided to try to convert the m4v files to mp4 via Handbrake. Problem is, Handbrake crashes every single time I try to convert a video. I followed this step by step tutorial, but to no avail. How to convert videos and transfer them to the HTC EVO 4G - Know Your Cell Any help is appreciated. Needless to say, but I'm pretty frustrated with this. Thanks in advance! Other than that, I love this phone. I'm a 3 year iPhone user since day 1 of the release of the iPhone and I have to say, I'm diggin' android and the HTC Evo.
