  Yes.
  
  Almost all Bluray players will play a UDF v2.5 with a movie on it, even if the physical media is a DVD.
  
  Something to keep in mind is that you can also encode in 720p, which is still *much* better than DVD resolution, which will let you can cram even more BluRay contents onto a DVD medium.
  
  Another twist is to encode the movie as AVCHD, which was originally meant for HD camcorders recording to DVDs. Many DVD (!) players and all Bluray players are compatible with this format, so if you encode your movie in this format, you have the unexpected benefit that it will work not only in Bluray players but in many DVD players, too.
