Thanks for the link.   Nice to know I am not the only one thinking this

But he never actually got the source code to check for this TV.   For
all we know, its running the xine engine for the signal processor.

I am in the FTA satellite world.   Some Linux based products like the
Captiveworks receivers are completely open once you spend some time with
them.   Some people have successfully hacked them without much work at
all and added a lot of fucntionality.

It shouldn't be too hard to port "top" and "df" to find out.

I'll keep everyone informed of my progress.
