While playing video files from a USB device on my BDV-F700; the subtitles disappear randomly during playback; usually at around 30-40 minutes. The video file (avi) and the subtitle file (srt) have exactly the same name; I'm using CP1254 (Turkish). If I go on to another video file on the USB device; or restart, subtitles appear again. Firmware revision number is M04.R.752 (latest as of today). This really gets annoying at times; I'd appreciate and ideas about fixing this strange behavior.
