Hi, with a few different movies in mpeg4 format with video, audio, and "tx3g" embedded srt subitiles, the Roku player will work fine if subtitles is set to "none" but selecting "Unknown (TX3G)" or "English (TX3G)" and trying to play it hangs for a while on "retrieving" and then says "Video Unavailable - we're unable to play this video, make sure the server is running...". Subtitles muxed in with Subler. MplayerX, QT7, QTX, and VLC handle the file without complaint.
