Hi Michael. I relaized the mode decisions favoring the intra coding when
RD is turned on, that was why I was turning it off: to get some
inter coded MBs for test. I thought of using one of the previous
versions, but I dont know if 61e(or others for that matter) is conforming
to the G050 or not. Do you have any knowledge of this? Thanks
Oztan
