Also try toggling the type of de-interlacing as well. I found that some of the deinterlacing types require more processing power, causing the choppy problems you describe.

Now that I've got MythTV back up and running, I'm back to try to fix the 
choppy playback.

My Liva machine used to play things fine. Now, there's an annoying level 
of stuttering. If ranges from frustrating to unwatchable.

I have tried both vaapi options in MytvTV. Both seem to give roughly the 
same results.

Is is likely that the current driver is simply worse, for my hardware, 
than an older one was?

If so, how can I try different drivers?

I have tried. I found a page that listed different i965 deb files, but 
they either didn't install correctly or did and didn't improve things.

I'd love get get the little Liva box working properly again, but I'm 
close to abandoning it.

Any tips?

Thanks,
Damian
