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.

Thanks Jay

I was on MythTV 0.29 (before today). I don't think that had many 
options, but I'll try all of the variables when I next can.

It seems strange that it has been running fine for years, but is 
suddenly really bad. The fact that it's also poor with loack files, and 
playing them through VNC, made me wonder about drivers.

Today, I've updated Xubuntu on my server, and updated MythTV from 0.29 
to 0.30 and then again to 0.31.

Now, can't even connect to the database (about to start another thread), 
so I'll have to come back to the playback problems.

Cheers,
Damian
