That works great Nico.

I found that for HD PAL (1440x1080) content vbuf sizes 333 and above
with an automatically-determined mux rate caused the mux rate to be
auto-increased to 16233.  With vbuf between 332 and 300 the final mux
rate increased to either 17857 or 19643, but the encoded file was still
fine. Below 300 the mux rate increased further, errors started to be
reported, memory started to run away, and the file was corrupted.

What would you recommmend for a program to record both SD and HD content?
A vbuf of 400 and auto mux rate, a setting for both vbuf and mux rate,
or should the vbuf setting change depending on whether SD or HD is being
encoded?  Should a vbuf of 400 cover all types of HD?
