Thanks Honza, got what I need, in.SeekCur(-2000);

About 40 bytes each line for 3D position, 1/sec.
To set the replay back 1 min (40*60)
in.SeekCur(-2400)

Works OK.

A file was used before for testing, CPU usage, responsiveness, etc for 50 concurrent traces for about 3 hours of data ~200k lines (8MB).
Fast forward was not a problem by skipping lines, in.SeekCur(4000000) could go to the midpoint faster.
Rewinding a set amount is a function that was not included before, now it can be.
