Add Track - zero duration?

[PhilaPhan80]

I tried posting this to the Basic Discussions board, but apparently user "HuggiL" hasn't logged in since April. Posting to this group since I'm not sure how else to do it if a moderator isn't present to approve my post.

I'm experiencing a weird problem that I just can't seem to figure out.

When I load some IFO files directly from their various source TS_VIDEO folders, I see their size and duration just fine. However, when I use the "Add Track" feature, some tracks match duration exactly while others show zero duration. There doesn't seem to be any pattern to it. Some load, some don't, but it's definitely more widespread than just one or two problem files.

Has anyone else run into this issue? If so, any solutions or guidance?
