said by Brano:Interesting. On good LTE connections I can actually stream from mapped folder via VPN (tried that with ES Explorer and MX player).
Your problem seems to be like MSS size related, did you try it from elsewhere (i.e. from other than home GSM cell locations?) Try manually lowering MSS for that particular VPN connection (It's in advanced settings I believe)
I will give that a try, and yes its at home. No I did not try elsewhere, what diff will it make? My next test is to try wifi at Timmies.
