Importing Chapters into TMPGEnc from XML files

[TheLaserdisc]

I have some MKVs that have chapter stops built in, how can I import these into TMPGEnc Authoring works 4 easily? They are in XML files.

<?xml version="1.0" encoding="UTF-8"?>

Basically, does anyone know a quick and efficient way to convert time codes to key frames for TMPGEnc Authoring works 4, or to convert those XMLs into keyframes.
