no, the bug is the the TS muxer.
if you run vlc --sout '#std{mux=ts,url=broken.ts,access=file}' 
TV1nieuws.mts vlc will
remux to a new ts the original file, and guess what:  broken.ts shows 
the same corruption
as in the udp stream, so in  this case neither mplayer's demuxers not 
its stream readers
are at fault
