Hi Carl,

> How do their streams look like with "ffmpeg -i"?

As a follow up I also ran ffprobe on the stream created by FFMpeg:

ffmpeg -i "c:\Superman vs Batman.mpg" -vcodec mpeg2video -pix_fmt yuv420p -vb 15000000 -minrate 15000000 -maxrate 15000000 -acodec mp2 -ac 2 -ab 224k -ar 44100 -f mpegts udp://192.168.1.3:10005?pkt_size=1316

This is the result from ffprob:
