Main problem here are copyrights and cost mixed... Chinese manufacturers started with AMV videos because AMV is a Chinese format, probably free of copyrights and cheap.
Then rockchip choose xvid instead divx due to cost of patent.
Seems that FLV patent it's not so expensive and probably supported by Google. FLV have been added in almost all players.
Only expensive Chinese player play divx, this format seems to be more costly than xvid.
Latest players have add Real video which is not so popular outside China, then patent too must be cheaper.
Expensive Chinese player have add too Quicktime video. All this formats added as a bundle!!.
Concerning rockchip who has rights over xvid, beside other Chinese chip manufacturers, some players makers for an unknown reason have choose to flip video, to make things more complicated. It could be that xvid would have put MP2 as audio encoder because this can be cheaper than with MP3. Seems that xvid / Mp2 is cheaper than xvid /MP3 which are used in more expensive players like Meizu.
Finally screen size implies a change in resolutions, which is also other complication.
As a general information the most expensive players from China are Archos. This brand plays several video formats without conversion.
