Stream capture

Hi,

My isp is giving iptv. Since they only give one stb for client and i live with my girlfriend, i had to dig into it.
They use multicast for streaming, so i wrote a little c program that joins the multicast group and wrote the contents of packets to disk.

The file can be found here:

Some of the channels, sd ones, i can basically watch by using vlc and connecting directly into the stream.
Some of them however, mostly hd channels, but also sd are somehow encoded/scrambled. The sound is decoded ok by every player, but the video is mostly squares.

By sniffing, i saw ISO/IEC 13818-1 is used, which seems to be the standard for this.

Is there any way to play this, do i need a new codec? I would appreciate any info about the file.

The STB has a bcm7406 chip. ( i opened it ;) )
