Sony 2011 NX723 TV Issues (Avi & Subs)

Just got a new sony 2011 tv (nx723) and installed serviio on the laptop, I have two issues...
1) Not all avi files were playing under the profile "Sony TV - 2011", The only way to fix this was to change it to "Sony TV". By doing this, am I missing out on any features?
2) I know Sony do not support SRT subtitle files (yet), but does anyone know a workaround fix?? I know ps3 media server supports SRT, but I coudln't get this to work anywhere as well as serviio with this tv.
Thanks in advance for any help...
