Nothing to worry about. The Fantasia on the 1990 reissue and 1991 VHS releases are one and the same, both running at about 119 minutes. Unless the theatrical reissue prints were played at 25fps instead of the intended 24, I’m not sure why someone would note that they ran 5 minutes faster than the VHS, because they most certainty did not. Disney, too, noted this on their anthology box set from 2000, and it is simply not correct.
Okay, thanks for the information.
