+ //and non-EOS.) The problem is when we set pCurr=pNext; when
+ //pCurr has the value NULL we interpret that to mean that we
+ //haven't fully initialized pCurr and we attempt to set it to
+ //point to the first block for this track. But that's not what
+ //we want at all; we want the next call to PopulateSample to
+ //return end-of-stream, not (re)start from the beginning.
+ //
+ //One work-around is to send EOS immediately. We would send
+ //the EOS the next pass anyway, so maybe it's no great loss. The
+ //only problem is that if this the stream really does end one
+ //cluster early (relative to other tracks), or the last frame
+ //happens to be a keyframe ("CanSeekToEnd").
+ //
+ //The problem is that we need a way to mark as stream as
+ //"at end of stream" without actually being at end of stream.
+ //We need to give pCurr some value that means "you've reached EOS".
+ //We can't synthesize the special EOS Cluster immediately
+ //(when we first open the file, say), because we use the existance
+ //of that special cluster value to mean that we've read all of
+ //the clusters (this is a network download, so we can't know apriori
+ //how many we have).
+ //
+ //Or, we could return E_FAIL, and set another bit in the stream
+ //object itself, to indicate that it should send EOS earlier
+ //than when (pCurr=pStop).
+ //
+ //Or, probably the best solution, when we actually load the
+ //blocks into a cluster: if we notice that there's no block
+ //for a track, we synthesize a nonce EOS block for that track.
+ //That way we always have something to return. But that will
