If an invalid pts value is detected, try to to make up some if it seems 

reasonable.
This avoids completely losing A-V sync e.g. when pts was not reordered correctly.
This was tested with http://samples.mplayerhq.hu/V-codecs/h264/PAFF/tv_cut.mkv
for this sample proper pts reordering is the correct solution, but more resilient
handling of the error case is still useful.
