How is your PI connected to your network? OTA HDTV can be up to 19mbs and wifi wont cut it for that...

I don't think that wifi is the problem... I've got the same problem and the reason is described in this thread :
http://forum.xbmc.org/showthread.php?tid=148646

It is a problem with the raspberrypi firmware.

I reported this issue:

Please add information if you have any and post your configs so that this bug get fixed .

The other thread concludes that this is an omxplayer error not a rpi firmware error
