Limiting the bandwidth did not help, either. I also increased the process priority of both PS3MS and mencoder_mt.exe, but this has not helped. Maybe I have a flawed version of mencoder_mt.exe?

I also have integrated graphics and no external additional graphics card. Could this be a problem, even though my processor speed should be more than sufficient?

Messing with my transcoding values for mencoder seems to help. These values seem to keep up except for in more action-packed parts of a movie:

keyint=8:vqmax=3:vqmin=2

Any ideas on how to definitively determine where the bottleneck here is?

Great news! It seems that downgrading my install to the latest official release (1.10.51) has fixed my issues. I guess there must be a regression in one of the transcoder builds somewhere that is causing my issue. Hope this helps you, shagrath - I've been reading elsewhere in this forum that the latest mencoder release seems to be causing issues for people, so I guess they are not alone. Thanks for all your time and energy helping me try to discover what my problem was. :)

Ok, I guess I was wrong. :(

The next video I've tried is having the same problem... going through some debugging steps to see what the issue could be (again). Drats.

shagrath - do you think you could add a couple debugging lines to the next release that might help determine where the bottleneck in a situation like mine is coming from? This would probably include adding in the read rate from the drive and the processing rate of mencoder, and anything else you might think would be useful or relevant.
