Youtube video plays but gets truncated

[Foxbat]

So I try to play a youtube video in what seem to be the standard way.

Open the youtube URL
Set an 'end' event callback
In the end event callback retrieve the subitem and play that

At this point I get video frames but only for a short while. The log file shows:

This seems to be success...

And at failure:

So what would cause the "mp4 warning: track[0x1] will be disabled (eof?)" and "core warning: can't get output picture" errors ?

Testing with this video http://www.youtube.com/watch?v=T7OYPb3fTP0 I get 66 frames and then libvlc bails. Other videos will play longer but will fail to complete.
