I am currently the proud owner of a Droid X, I love my phone and being able to use it to the fullest of its ability. I wasn't able to find a thread that address my problem so I'm hoping someone will be able to assist. I have figured out how to put music videos with a MPG4 format on my phone. And most of the time they play. But I want to take it one step further. I currently have a digital copy of Iron Man 2 in MPG4 format and for some reason the file will not play.Whenever I go to view it an message pops up that reads, "File cannot be displayed or played". Now I know it has nothing to do with memory because I still have 10+GB's left on my SD. And like I said the file type if the same as the music video's I have so why would this be a problem. Any suggestions for Movie playing apps or any suggestions at all would be helpful. Thanks you for your time and I hope to hear good feed back soon.
