1) Not really a question for the developers list :-(

2) There is only so much bandwidth in a PC,
and I suspect mergedFB is using a lot of it.
Have you tried lower frame rates or resolutions?

3) Ditto for deinterlacing.
Try disabling, and note any improvement.

4) Is this a standalone frontend? Or combined?
Are you using XVMC?
