Glad it works.

I suspect method one does not work as it's not the correct way to patch things up. So the episodes menu is the only one that has problem? If so, that is odd indeed. I don't know why it's different, probably due a minor improper menu authoring.
I used the Muxman Pro version but the free version will do. Actually I use more programs than MuxMan for method 2. I first extract the menu background with VobBlanker and the 2 subpicture highlights with PgcDemux by vobid. Then mux the background and the 2 subpics with MuxMan, choosing 16:9 dislay, into a VOB file. Now it's time to export the buttons and the color schemes of the original menu for safekeeping using
DvdReMake Pro. Then replace the newly muxed menu over the existing menu in DvdReMake Pro and import the buttons and color schemes back in. You can also do the export/import of buttons and color schemes and replacing menu with PGCEdit as an alternative.
And that's it.
