[vdr] Re: shell script for data rate calculation

[Gerald Raaf <graaf@attglobal.net>]

Hi,

i've got some movies (~105 hours) and test the data rate calculation. As you can
see in the output, the movies with dolby digital and normal Sound have a much
higher datarate.
So we can assume movies with DD have a rate of ~4600 kbps.
