I have been trying for ages and googling all forums and with no luck untill now. I have two tablets each with different firmwarw one was #121 and other #142. if i tried to add a server through lan on es explorer on #121 i had to do it manually and it would never work whetever the settings, but on #142 when you go to add server there is a search button and it serches succesfully and finds my pc. all I need to do is put in my username and login that i use for my pc. Success, now i could find all my lovely avi files put low and behold it would not play any until i found pinochio. This video was the same codec as the others same bit rate etc so why did this play?? It plays because the file extension .avi is in capitals . AVI so i renamed the rest on my pc and viola all sorted. I did try this with the android official hiapad2.2 version but i could not get the menu option up in file explorer to add a server. Any way to may your avi's play through es explorer rename the extension to .AVI not .avi ps. Also for some reason i need to have an sd card in the slot other wise it wont play either.
