Problem with Sharp 40LE830 3D TV

I've recently bought a Sharp 40LE830 3D TV. I watch movies or videos clips via usb flash memory, and have two problems:

1. srt subtitles are not displayed, although srt file has the same title as the video file and is in the same folder. Is this TV supposed to display srt subtitles?

2. Auto 3D detect option is on, but doesn't work. It's not a big deal when the 3D video file is side by side or top and bottom, because I can manually set the TV on 3D mode. But when the 3D video file is frame-packed, I have no way of setting the TV on 3D mode, and glasses don't work. How can I watch these kind of movies?

No, AFAIK

Serviio doesn't do anything special for 3D movies. It works with SBS, not sure for the frame-packed. There is nothing in DLNA to tell the TV the content is 3D.

So there's no way to watch a 3D movie like this with this TV? http://s3.picofile.com/file/7554838167/Avatar_3D_Sample.mp4.html (16 MB)
