I have had problems playing back CD's also burned in CDA5. I have now found a method that works, Sort out all of your tracks as normal in CDA5 but do not burn a cd in CDA5. Instead save the project as a.wav file instead of a .cdp file. THis will save your entire project (including all crossfades, indexes etc) to one master wav file. Then by using the premaster utility (which can be found at http://projecteva.net) open the master wav file in it and then save it as a.cue extension (same as a iso image file) It will recognise all the indexes and then you can burn this image by using either nero or roxio etc. I burn mine with Nero express and all my D's work fine now. I hope this helps.
