MP4 playback almost freezes when i enable greek SRT subs

The workaround is to disable the SRT subs for a while and the enable them.

I noticed that this happens with mp4 files Mediainfo (not all of them):

MMh, this happens with embedded subs or external? The latter sounds very unlikely, can you upload a sample to sendspace or mediafire?

This happens with external SRT subs with the latest firmware. Send me a private message to send you the link to the movie if you want. This also happens with isx/sub subs also. I notised that it occurs on fast scenes more frequent.
