Well, i know how to recompile VDR but (eventhough this might be a stupid
question): How do i define that i have a 4MB DVB card? I am using the Linux
driver that comes with Suse 9.1 (not CVS) and Firmware 261d. To use the
extra 2MB SDRAM i found a hint at http://www.vdr-portal.de saying to change
--- snip ---
#define MAXOSDMEMORY  1000000
---snip ---
from the default 92000. I guess this does not help in 1.3.21 to use the

How and where can i configure
1. a statement OSD_CAP_MEMSIZE and

Maybe in Make.config? Or in dvbosd.c / transfer.c? Like i said, i am using
some old linux dvb drivers and i can not update to CVS for various reasons
at the moment.
