Attention audio/video guru's ? re. dvd-audio

It seems that my reasonably new and reasonably expensive dvd player has decided to only pickup the dvd-a layer when it has the option of both dvd-a and dvd-v I know when I first got it I could access both thru the on-screen menu but know it defaults to the dvd-a and won't let me get to the other layer,it is not the end of the world but I like the dts surround mode sometimes and I can't seem to get there anymore it just forces me to use the pcm mode I just know I am not alone and one of you can point me in the right direction
Check or Replace the batteries in your Remote for starters.
Here's another example of how the DVD standard is in such disarray. The hardware and software people can't get together and figure out a standard system for disk navigation! DVD will live on for video, but it is a failure so far for high resolution audio.
Dvd audio defaults to dvd audio so that you don't have to go into the player menu each time you play a dvd audio disc. Set the player menu to output DD/DTS in bitstream. This may help out.
