Seems normal (the minor should be the same as the video device number) > > Is there something in the database that needs to be changed to get the > second card working? > As long as there are inputs defined for the card and they are attached to the input(s) this should be OK. (Check this thread for more details http://www.gossamer-threads.com/lists/mythtv/users/54074) However, if you can afford to remove the capture card settings altogether and the redefine both cards it may help if there is a DB problem. Are you able to cat both /dev/video0 and /dev/video1 into an mpg or directly into mplayer from the command line as per Jarod's guide? If not, the problems are at a lower level than a problem with myth and need to be sorted before myth can be fixed. (These could be udev or modules.conf related to the ivtv driver options) Nick _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
