If you're playing over http then data not being available should lead to
MPlayer blocking until it is available, not MPlayer proceeding without
using the information.

Does the captured file cause a lockup if you play it over HTTP (from a
web server)? If not you could try directly capturing the original
content with wget for example to make sure it's the same as what MPlayer
playback sees (though I think -dumpstream should do that).
