Miro no longer uses hardware acceleration?

I have been using Miro to watch my video podcasts for years, and I until now Miro has used GPU hardware acceleration which kept my CPU usage (and generally the CPU temp) down.

But for some reason I just started playing some videos today and noticed the playback frame rate wasn't as good as it used to be. It looked pretty jittery and was quite noticeable.

Looking at my Activity Monitor, Miro was doing about 120% of my CPU (one core and some).

If I play the same exact video in Quicktime, it does about 8% CPU usage.

That's not a small difference.

Anyone else experience this recently? I don't know what might have changed the behaviour.

The only thing I can think of is that just recently one of my RAM modules went bad and had to be replaced so I went from two 4GB sticks (8GB) to one 4GB and one 2GB stick (6GB) so I am no longer dual channeling. Would this have an affect on playback in Miro?

Apple probably changed something and Miro no longer uses the correct way of accessing hardware. An update will likely fix this in the future.

Possible, but the reason why I was asking was to see if anyone else was experiencing the same thing.

I don't recall doing any software updates (for either Miro or OS X) when I noticed it changed. Unless I'm going crazy, the only difference is now I have 6GB of RAM instead of 8GB, but that shouldn't be the issue.
