Well, yes. For example, the DD+ on the HDDVD and the DD on the BD version of Batman Begins are bit for bit Identical but just labeled differently: i.e. one of them has a + and the other one doesn't. But don't confuse that with the regular Dolby Digital found on the DVD version as both the HDDVD and BD versions still have a higher resolution.
