I did that. I forgot to mention that I did "rmmod bttv" (and it's friends tvaudio and tuner). Actually my goal is to get Matrox Meteor-2 working too. We use both Matrox and Hauppauge hardware, depending on application. .. So even if there are no modules loaded, "modprobe videodevX" fails, giving that same rap about it's unability to get major 81. How could I find out if someone has taken that major 81 already (who took it)? > Do "modprobe bttv2" first. > > modprobe bttv will load videodev which will take 81. videodev won't load > bttv2 so it needs videodevX. videodevX needs 81 so it won't load. > modprobe bttv2 will load videodevX. videodevX will take 81, but > videodevX will allow bttv to load, so no problem. > > Bill. > > > Joni Kähärä wrote: > > > > Good day everybody.
