XML is case-sensitive. Your second activity has an <Activity> element, not an <activity> element.
Also, your path to your video file is doubly incorrect. What you have in there now is a reference to a file on your development machine, which is not valid for the emulator or the device. The path you have commented out is a bit closer, but never hardcode /sdcard as a directory, in large part because it is wrong. Use Environment.getExternalStorageDirectory() to get a File object pointing to external storage, and use that to construct a path to your file.
