I have not been able to pull TV show info from the web with this build at all. I have tried both TheTVBD and TV.com. This seems to be related to the regXP but also tried several different versions. Movies from IMDB, music, and music videos work fine.
I store all my TV shows as: <Name>/Season <n>/<Name> s??e?? <title>.<ext>
Here is a snapshot of one of the logs from a clean install (not tampered with or merged):
