[vdr] ATSC missing program discription on some channels

[Timothy D. Lenz]

Using the ATSC epg plugin I get all program names, but some channels 
just say no information. But if you check the same channels with a 
converter box, they do have program information. I was told there is a 
flag that is checked. If the flag is not set by the broadcaster, the 
program info is not looked for. Need a patch to disable the check and 
always look for the information.
