VLC 3.0.8 bug kill on BTVlink 4.9.3.6535 on Win7pro64

OBSCURE BUG and treatment
vlc-3.0.8-win64 appears to have a problem with BTVLink Vers.4.9.3.6535 (2010)
Upon opening various recorded files (*.tp), image was ZOOMED to the extreme. . . in the BTVlink display.
When I tried to test display the file in VLC, it, too, was ZOOMED to the extreme.
This behavior was not seen on other HTPC machines.
After wasting time re-installing BTVLink, problem persisted.
I downgraded to vlc-3.0.7.1-win64, and both programs can now properly display video files without error.
