TMT requires you to have the requisite folder structure from the disc, otherwise it won't let you choose the folder. Network access via mapped drive and share works fine over there.
DVD's require the content to be in a "VIDEO_TS" folder
Blu-Ray requires the content to be in a "BDMV" folder
For example:
X:\Media\Movies\Die Hard\VIDEO_TS <files go here>
Then when you pick "Die Hard" in the UI, the OK button will enable. Let us know if that did the trick or not :)
edit: should have read your original post closer. You already have this set up, huh? Then I'm stumped as well. Sorry man.
