If VDR does not work at all, but other tools are working, it could be compatibility issue between VDR and Kernel. # tune to channel: szap -r "CHANNEL NAME" # dump channels from tuned multiplex (if you don't have that command just skip): scandvb -c # save tuned channel to file (lets say 20 second): cat /dev/dvb/adapter0/dvr0 > test.ts # check if ffmpeg finds video and audio ffmpeg -i test.ts and post result here regards Antti -- http://palosaari.fi/
