[MPlayer-users] Weird behaviour in ide-scsi driven dvd playback with 2.6.17.x

[Marcin 'Rambo' Roguski]

Because of USB camera requirements, I'm currently running double-kernel 
setup (2.4.32-old, 2.6.17.9-new), and ide-scsi driven CD-ROM/DVD drives.

and so on...

The only workaround for now is to use ide-cd, and then it works like a charm, but I'd preffer "unified" setup (unless mplayer can use conditional statements in its config...
