I think requiring AVSEEK_FLAG_ANY just side tracks the issue and could break
some apps. I added a comment to ticket 1607.
The way it works now is slightly broken and not convienent to work around
but its close. It does seem like it should be more or less busy work to get
it working probably. I say busy work because I think the seek code would
need to be specialized somewhat to work in this case rather then using the
generic seek code. I am guessing a bit.
