ReauthoristLog/ecl errors?

[shoarthing]

Hi - the 4U's have worked perfectly & reliably in the past; now, in a new XP SP1 install, with same version [1.0] of Reauthorist, bitrate info is - er - a trifle screwed:

[from ReauthoristLog.txt]

"M:\FOTR_4U\VTS01\VTS__01_P01.I-BFF.16~9_1.AVS",0,9160,4673072,0,3

23:44:24 Encoding list:

"M:\FOTR_4U\VTS01\VTS__01_P01.I-BFF.16~9_1.AVS",0,9160,2944018,0,3
"M:\FOTR_4U\VTS02\VTS__02_P01.I-BFF.4~3_1.AVS",0,9800,15819,0,3
"M:\FOTR_4U\VTS02\VTS__02_P02.I-BFF.4~3_1.AVS",0,9608,6671,0,3

- these are not parameters CCE is going to be happy with.

Any ideas as to which exact obvious operator-error boob has led to this?
