5 AVI has been around a long time. It is inevitably prone to "bitrot", then.

7 AIUI the AVI specification states a number of valid codecs that can be used; AIUI h264 (for example) is not amongst them.

9 It will work on some systems (particularly open source) to put h264 / AAC into an AVI - that's not supported on others. So if you need to play the video on a Mac, a games console or a set-top box then you may be in trouble.

11 As a rule of thumb, most new video-playing devices have hardware h264 support; use .mp4 or .mkv for h264.

15 If you merely renamed the file then you didn't change the container.

19 A Linux video player will probably ignore the file extension - it'll figure out what kind of container you used based on the file's header bytes and on the file structure. The default video player installed on Windows or Mac may not be so clever.
