[FFmpeg-user] mpegts: all programs empty

Hello all. It seems ffmpeg from git has problems identifying the streams 
in the programs of mpegts files. For example, excluting:

ffmpeg -i mux1-cp.ts

I get the output contained in the mux1-cp-git.txt attachment: all 
programs are "empty", everything grouped in the "no program" section.

But if I execute the same command using an old ffmpeg it produces the 
output contained in the mux1-cp-old.txt attachment.

ffmpeg is compiled on Windows with a fully updated mingw32.

mux1-cp.ts comes from:
http://www.pjdaniel.org.uk/mpeg/downloads/mux1-cp.zip

but the same happens with most videos I tried.

Any hints?

Thanks,
MRC
