Playing recorded DVDs on a PC -- menu problem

Finalized DVD-Rs from my LiteOn LVM-5005 cannot show any menu pages except the first page (showing titles 1-6) on either of two PCs tested. The link to the next menu page, or the ‘title view’ option do not work. Neither Windows Media Player nor PowerDVD can navigate to the second menu page. The titles themselves can be accessed by navigating the chapters forward, so there is some functionality.

Anyone else experience this? Could it be a brand issue (tested with TDK DVD-R)?
