Yes, that's the key.

Whether you use mythbackend or mythfrontend to call --version, it will 
say using_vaapi if it was compiled to support VA-API.  The backend 
doesn't need any special support for VA-API--you just have to have 
MythTV compiled to support it.  I just had you use mythbackend to find 
out how your MythTV was compiled.

So, you'll just have to find a version of MythTV that was compiled to 
support VA-API.  I don't know if *buntu quit compiling in support 
because it's not very functional or if there's more to the story.
