I did check the VHS but I didn’t find any difference between the WS VHS and the Laserdisc.
So if the VHS is altered, that means that the LD (and the VCD, the ORF1 broadcast, the Scandinavian C+ broadcast) are also altered. That would mean that there is no theatrical reference at all for TPM: that would be a brand new information with huge consequences on ongoing projects.
That is the reason why I’d like to get evidences, no offense to Jay.

JEDIT: I also captured and checked the VHS “For Your Consideration” (made in 2000 for the Academy Awards): it is exactly the same master as the public VHS and the Laserdisc.
So if the VHS was altered, it was already done in the first months of 2000, and the jury of the Academy Awards didn’t see the theatrical version.
