[vdr] Re: Transfer mode

["Tilo Renkl" <tilo@diredare.de>]

Hi Klaus,

as you suggested I tried various values for that usleep call between 10 and
100000, but
it is allways the same CPU usage between 5% and 80 %.

Sometimes CPU-usage is 5 % for about 20 secs and then 80 % for the next
about 15 secs ...
