I never thought of using two frontends - nifty trick though.

If I were king for a day...

Drop down to select video renderer (i.e. VDPAU)
Text box to specify options (i.e. vdpaubuffersize=32)
Number of CPUs to use
Directory of video clips you want to test
Number of seconds / test

Then a big button that says "Go".

The system would then run through all the deinterlacers for each of the
clips specified for the duration stated above. Detailed log files would be
dumped to the log directory already provided within setup. Lots of
information could be reported like list of errors, average CPU load, total
dropped frames, audio buffer under run, was the test successful, etc.

Anyone else have some thoughts on this?
