scheduler interface

[derevo]

tv channels always report start and end time of programm, not duration.

for example, so:

10.00 news
10.20 film american pie
12.00 formula 1
13.45 popstars

and I have always to calculate duration of program to enter it to scheduler of dvbdream.

all other (dvbviewer, progdvb) receiving programs has traditional interface of scheduler ie start and end time, not start and duration.
