VideoGrabber.CompressionMode = cm_CompressOnTheFly
There you go. CompressOnTheFly can't keep the pace of frames coming in.

I would avoid any transcoding while capturing.

I would suggest to capture in native source format
(only this should be called capturing, IMHO,
the goal should be to get the source to HDD frame by frame, not risking any drops,
no conversions attempted, we have time to do this later on)
or if one can afford the storage space, as uncompressed.

Any MPEG-4 AVC takes so much processing power to encode, especially for HD sources
that encoding really should be the final step before delivery.

If one attempts to encode HD resolutions to H.264 in realtime, so online,
the final quality will have to suffer compared to what would have been available if encoded with slower settings and offline.

Here x264 blu-ray HD encodes take some 0,7..2.5fps per pass, CPU and commandline depending.
No heavy Avisynth filtering included (!)
