Thanks, that works.

Above is the relevant lspci output. When using the built-in Intel video controller I didn't have any performance problems in that regard but I was limited to an X resolution of 2048.
The Radeon HD 5450 is a modern GPU - it definitely supports hardware decoding of all the common formats, as well as the previously-mentioned hardware image scaling - and you can get it to do hardware filtering to improve the video as well. You want to Google for "VAAPI" and "XvBA" to learn how to enable that on your Linux system.
video and audio out of sync and for some other videos the resolution isn't
the latest addition to my ever growing mplayer alias is -autosync 30 which does a pretty good job of keeping audio and video in sync.
this wasn't needed with a previous kernel/x/mplayer version, but for some reason I insist on doing 'yum upgrade' and breaking things :) if it's your video that's slow, you could also try -framedrop
Video is the problem so I'll try -framedrop. Thanks for the suggestion.

Seriously? Hardware acceleration for rescaling of video (ie. upsampling so you can display it full-screen) has been supported in X and mplayer for a very, very long time.
I also note that even a low-spec, first-gen core 2 duo from 2006 can play back 1920x1080 h264 video (just); so can the slowest Celeron (E1200) from that era. I know because my last media PC had one.
I've had discussions on this list on similar topics on more than a few occasions, dating back to when a P4-1.5GHz was a reasonably powerful system.
It seems that every time I test such things I find that Intel video controllers give better results which is apparently due to having better driver support for scaling. Such discussions usually end up with several people trying to convince me that I should buy better hardware in spite of the fact that my system is mainly used for xterms, email, and web browsing. With playing video being the only task that taxes the display system.
I can cope with a small video window centered in my large monitor.
