Frame rate reporting bug?

[Akodo]

Much to my surprise I was able to play a Hi10p video without much issue on my Pi. (There was only slight artifacting in certain scenes) I decided to dig a little bit more and noticed something strange. When I went into XBMC's codecinfo (the o key on the keyboard, look at the row that starts with W), it was reporting around 10fps +/-3fps. The video didn't look like only 10 fps so I decided to try a few other videos that were not 10- bit encoded. Both 1080p and 720p h.264 videos showed up once again as <10fps in codecinfo. Can someone else check their video files to see what the output from codecinfo is for them?

Also, what's the current status with xbian for hardware decoding. I haven't been able to find any solid answers about that. Thanks!

EDIT: rechecked, I'm actually getting a HIGHER average reported frame rate from 720p 10bit video than from a 720p 8bit source.
