Quick Starting Point
The Motorola Droid is quite the fancy piece of equipment. It has a QWERTY keyboard, solid design (other than the SD card being under the battery) and a large beautiful display. Surely you want to do more with that display than simply scroll through menus and make phone calls with it. Oh, the other Android phones may be able to play some video too, but it won’t look nearly as nice as it does on the Droid. There are a few ways that you may watch videos on this phone: you can hook the phone up to your USB port and copy files to the SD card, you can get on YouTube, or you can download applications that load videos for you.
Just for reference the playable media formats of the Droid are: AAC, H.263, H.264, MP3, MPEG-4, WAV, WMA, eAAC+, OGG, AMR WB, AMR NB, AAC+ and MIDI. This means that if you want to play a file that is not in one of these formats that you need to either convert it (Media-Convert or Convert to MP4) or find an app that will support it. There is an AVI player app that I know of for sure, but it is best to have the files in the proper formats. Three good video apps are: TV.com, Jetflicks! TV, and Television.
