Updated file format list in https://sakaiproject.atlassian.net/browse/SAK-23207#icft=SAK-23207 to list the formats supported. Others may work but not be completely compatible.

elect a .flv, .f4v, .mp4, .3gpp, .m4v or .mov file

I don't really think this is a regression, the movie plugin only supports a few select video formats. Sakai doesn't have any capabilities to convert formats. I have an open ticket to update the list of extensions. Really out of the ones you tried only flv and mov should be expected to play, not wma, wmv or avi. Those might play, but it's very OS and Browser dependent. The best advice is to use something like Handbrake to convert to mp4, then it would play on anything and it's about the same file size.

See SAK-23529. With the FF plugin and setting the files to publicly viewable will allow them to play in FF. Tested on Win7 using FF20
