[Alessandro sordoni]

Hi,

thanks for your answers.
Do you think i can solve the problem with pcr or it is better set up a
videolan solution without using vdr then? the architecture that
results will be:

signal --> dvb card --> linuxtv drivers--> videolan ----> aminobox

is it right?

thank you all again
