For me 0.21 was working fine, SD MPEG2 playback ticked along at 30-40% 
CPU. Upgrading to Ubuntu Hardy caused xv-blit rendering to be unworkable 
and opengl rendering to use very nearly 100% of my Pentium 4 3.2GHz 
processor and stutter every minute or two.

I'd like to hear if anyone has any other suggestions how I can fix this 
on the hardware I already have that worked last week :-/

P4 3.2GHz processor, 2GB RAM, ATA Radion 9200 PRO, Myth frontend and 
backend on same box with recordings on local 7500 RPM SATA 750GB drive.
