How exactly are you watching the 'build'?
Um...... Build to Disc then play the disc or Build to Folder and playback with one of ny media players.
I'm not sure I understand your question. Other than via Preview, how else would you watch a project created in Encore?
The most frequent problem here is incorrect pixel size and/or par of the menus.
PAL or NTSC?
When you right click the menu and "edit in photoshop," what is the pixel size and what is the par?
720x480 DV NTST Widescreen [1.21 PAR] which is the default "Blank Menu Wide" from the Encore library for widescreen menus which is what I have ALWAYS used in Encore CS3.
I have found a workaround to get my project completed in time to meet my deadline:
I constructed the menus as DV NTST Widescreen [1.21 PAR], like always, but once completed I changed the PAR to standard DV NTSC [0.91 PAR] then imported them into Encore and set the menu display to 16:9 in the Menus Properties Basic tab.
While this solved my immediate problem and the menus seem to work fine now, it make absolutely NO SENSE to me.
Why would the output directly from Encore's own library NOT work properly within Encore? And why does bastardizing the menu shape/PAR into some "Frankenstein" appearance in Photoshop now make it acceptable to Encore?
