FIRST of all thanks @Peter Ross for fixing the seek in WTV files.
Summary of the bug: When I try to convert TS files to WTV files and if the
converted file is > 2GB, it is unplayable.
How to reproduce: Here is a very simple remux from TS to WTV, as you can
see the conversion itself is showing no errors, but if the destination is
> 2GB the file is not playable by WMP, however if I use a smaller source
so the destination is < 2GB it works fine (same settings).

I'm marking this important since it's fundamental issue, but if my
analysis is incorrect feel free to change it.
