The trunk version no longer contains that error message. Assuming you really did compile the trunk, check the files installed into the correct place. On my setup (Slackware 8 upgraded to 12), the ivtv X driver gets installed into '/usr/local/lib/xorg/modules/drivers/', but by default X is only looking in '/usr/lib/xorg/modules/drivers/'. You can either move the files or edit the module path for X. > So I have two points of confusion: > > 1) When the next version of everything comes out, will this be > significantly better than fbdev speed-wise?

MythTV should work fine with ivtv 0.10.x Personally, I no longer use the mpeg decoder, but let MythTV use the Xv overlay instead (not available with fbdev). > 3) Is there a combination of kernel/mythtv/ivtv that I could revert to > to take advantage of TV-Out today? If you want to use the mpeg decoder within MythTV, Linux 2.6.21.x & ivtv 0.10.x should work fine. If you just want to use the Xv overlay, then Linux 2.6.22 is fine. Either way, the trunk version of the X driver should work fine, -- Ian _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
