[MPlayer-users] Re: RH8: Can't Use VESA, Even As Root

I had the same problem with my mandrake 9.0 using the vesa output as 
Xavier described in his posts.
I could finally run mplayer using vesa output after I had downgraded my 
glibc-2.2.5 -> glibc-2.2.4 .

I have one problem through, I couldn't get my tv-out working with ATI 
Rage 128 card. I plugged the cable into TV after booting the system.
Isn't it so that the ati card has to be switched manually using the 
atitvout tool? I cannot use that tool as test.sh fails for all tests as 
it seems to me. I cannot switch also to PAL system using that tool (I 
assume it's needed)? It nevertheless shows some not easily identified 
figures on my TV as I put the TV to auto search the channels but the 
auto search skipps it.
Have to figure it out what I'm doing wrong with TV output. Is there 
tools/a way to detect the tv-out is supposed to work but the problem 
lies in cable or card setting?
