yes in my case anyways the built in video library on the main menu for gb-pvr and the version is 98.8b. I just installed it a few minutes ago. I do not however see a .dvd file listed. That may be the problem.
On my setup I have C:\DVDs\AceVentura\VIDEO_TS containing the IFO/VOB files. When I use the Video Library and browse to C:\DVDs\AceVenturait detects the VIDEO_TS subdirectory and displays the this fake .dvd item for you to play.
Here's the path I use: \\Mediaserver\d\DVD Master Directory\24 DVD\24 Season 2.2 UP\Video_TS that points WinDVD to the Video TS folder, but WinDVD won't actually start playing it. It just sits there. I can play it from Video Library, but that's not what I want; I want the controls that WinDVD offers. Any thoughts?
