I'll deconstruct it for you...

61418 [b]: 76733,76733..........2 *

This represents picture number 61418 of the coded MPEG stream (not the display frame numbering, which can be different due to pulldown). It is a B picture. Its fields appear together in display frame 76733. The 2 at the end is a bitmapped indication of the TFF/RFF flags. Bit 0 is RFF, bit 1 is TFF, so 2 = binary 10, which means this picture is TFF and is not pulled down. That is why there are only 2 display frame numbers shown.

61419 [b]: 76734,76734,76735....3 *

This represents picture number 61419. It is a B picture. Two of its fields appear in display frame 76734, and one (pulled down) in 76735. TFF=1 and RFF=1.
