I am running Air Video server 2.4.3 on Windows 7 x64 and Air Video on an iPad 2 (iOS 6.1.3). This setup has been used for a long time and subtitles have been working OK. However, the last files playing have not shown subtitles. I can select it from the Subtitle drop-down (Unknown language srt) and it plays OK in VLC on the PC, but not showing i Air Video.
I have read most of the threads about the same issue, and made sure the 'Allow H.264 Video Passthrough' is turned off.
The strange thing is that most of my movies play back fine with subtitles, but some titles will not show them.
Attached is one of the subs not showing.
