I don't think we should break SRT compat for this. I don't think this is a  
problem at all. We already have this situation elsewhere, e.g. what if you  
do <link rel=stylesheet href=movie.webm>?

If it really turns out to be a problem you could just apply the hardware  
limitations clause and abort parsing if you haven't found any cues after  
parsing X bytes or whatever.

In any case, the spec currently requires text/srt (or other supported  
subtitle format MIME type) for <track>, so a movie file would be rejected  
based on the MIME type per spec (see step 4 in  
#sourcing-out-of-band-timed-tracks).
