Egreat were known in the 1185/1186 media player era for crappy hardware quality and providing no firmware updates.
Since then (4 years) they have struggled with a series of poorly received Android boxes also featuring poor hardware quality and firmware.
The A5 plays Blu-Ray menus using Vidon, it's nothing to do with any work Egreat have done! Other boxes do the same (and I think HiMedia Q5/Q10 Pro could if you buy the VidonHD player): http://vidon.me/vidon_xbmc.htm

Sample quotes from their own forum (in case they get magically deleted in future):
Tom hasn't been seen since early August. It's a shame. I know I won't be buying any Egreat products in the future. This box has magnificent hardware, but the software is a major letdown. The Vidon.me membership is worthless because it can't do hd audio on this box. So disappointed.
Attention to potential buyers. Stay away from Egreat company. Is not what it once was. I try to play an old movie in avi format with internal player. Guess what ? Unsupported format. I also have an old Egreat R200 Pro (much better support at a time )
