Hi, for those who like to upgrade their full-featured DVB cards to 4 MByte SDRAM, I've uploaded some information, how this can be done.
See http://endriss.escape.bei.t-online.de/dvb-mem-mod/index.html With this modification, vdr has a full-screen, 256 color OSD. Special thanks go to Carsten Koch for donating a broken DVB-S card for this project, and to Klaus Schmidinger for modifying the firmware to support DVB cards with 4 MByte SDRAM. Have fun, Oliver
