Well, the mpeg2 syntax allows for streams up to 16383x16383 I
think. However most streams follows one of the published profiles, and
the highest ones are at 1920x1152. But, it is always possible to make
a stream that doesnt follow any of the profiles.

The problem right now is that libmpeg2 uses a limited-size buffer to
store data chunks - and the size of that buffer is determined by the
highest profile and level that we support. So, just increasing the
resolution would not be enough to support these streams, we would need
to increase the buffer size too...
