LAV frame dropping but MPC Video Decoder (Gabest) ok ? (1 Viewer)

[EditBear]

I may be posting in the wrong place - if so, forgive me and point me in the right direction please.
I have downloaded LAV filters as part of SAF - for use in Mediaportal.
I am using LAV Video Decoder for MPEG 2 standard def British TV. I have the display refresh rate at 50Hz.
I get frame dropping about once a second when using the LAV Decoder - but everything is OK using the MPC-MPEG2 Video Decoder (Gabest) Decoder.
Pressing Shift-1 in MePo shows the red line dipping sharply as the frame is dropped using LAV.
But the red line is flat using MPC-MPeg2 Gabest?
I much prefer the quality using LAV ( the crawling roller of BBC News 24 is blurred with Gabest) and anyway, Gabest is not available in HD - so help would be appreciated please.

Upgrading to Mepo 1.3 Final has solved this problem.
Many thanks to the MePo community.
