I'm running Centos 6.5 and smplayer is having big problems with frozen playbacks or playing back very fast, on all videos that I have. (These videos play back just fine on Fedora systems or Windows.)

It does it on Centos whether I'm using smplayer or mplayer, Dragon Player, or even VLC. I've used every renderer that s/mplayer has (x11, gl, glnosw, gl/ati, etc.)

I've tried reinstalling the entire mplayer system plus the codecs, to no avail.

My card is an ATI-based card.

Is there any solution that is known for this problem? Thanks!

how did you install mplayer and vlc ?
there are a few INCOMPATIBLE repos like linuxman and rpmforge
only vlc1 is in the cent repos

for vlc2 you NEED to use a INCOMPATIBLE repo

also what version of ffmpeg ?
if it is a old version then it is single threaded and not multithreaded

What ati driver are you using ?
the open or closed source one ?

please post the driver version and the repos you are using

You're probably right, I actually use VLC in another virtual machine because it won't install on this system directly. But strangely it has the exact same problems.

I believe I am using the open source ATI code...

from the pastbin link( no need for that just use code tags here )
"livna" is no issue there is only ONE ( 1 ) program in that one "libdvdcss"

as to the repos please READ the wiki page
http://wiki.centos.org/AdditionalResources/Repositories

now multimedia is in "rpmforge" it is ALSO incompatible with the cent base and update repos
( not as bad as it was with cent5 but there are still issues )

"epel" should be fine BUT might have problems with rpmforge

"PlexRepo" i do not know that one so .....

"atrpms" -- rather BAD !!!
this one is KNOWN to be incompatible with rpmforge and WILL CAUSE PROBLEMS !!!


"linuxtech"
known to be incompatible with base and rpmforge

the good news and the ? maybe ? bad news
there is a plugin that will mostly PREVENT rpmforge from replacing CRITICAL SYSTEM FILES

the Priorities plugin
http://wiki.centos.org/PackageManagement/Yum/Priorities
BUT YOU HAVE TO CONFIGURE IT !!!!!!! -- yes all caps and bold , it is important
1 is the highest Priority
99 is the lowest Priority
keeping "rpmforge" at 99 and epel at 90 then "base" and updates" at 80

you should be fine


now the "bad" part

rpmforge AND ATrpm might have ALREADY REPLACED CRITICAL SYSTEM FILES
and might be fighting with each other

we will not know that until the Priorities plugin is installed and configured and you run a update
then set it up and the repo files
then update


but from looking at that "pastbin" output of "
"yum repolist all"
it looks like you did not read or fallow the warnings about adding every and ALL repos and mixing it all up in one big pot
-- this is not good and will cause PROBLEMS
