From other group by

The disk is formatted by the 622 so that contains two ext3 partitions
with a normal (non-GUID) partition table (example below for my 250 GB
disk):
Code:
Device Boot Start End Blocks Id System
/dev/sdb1 1 132 1060258+ 83 Linux
/dev/sdb2 133 30401 243135742+ 83 Linux
On the second partition, there is a directory named
DishArc that
contains folders for each program with 8 character hexadecimal names
(example
1e0f2000).
Inside each program folder there are 4 files:
bm,
cat,
tsp, and
wtt
The
tsp is a large file (910 MB for an hour SD show), while all the
others are under 4k. I am not sure at what size there might be
multiple
tsp files.
I've run
tsp trough dvbsnoop and it appears to be standard transport
stream with the TS packets scrambled (transport_scrambling_control set
to 0x02 or 0x03 on several TS packets).
the
cat file has the program description data, and
bm has some of the
same information as
cat but with some additional information at the
end (perhaps to provide context for the decoding of the transport stream).
Finally,
wtt has some repeating data that i can't decipher (repeating
hex f8 23 6e 38 followed by another 8 bits that change every few lines).
