The questions you have asked need to be asked of the other program companies. As stated on the product page for Keyrite, it can use either BIN or CDG (same formats)for karaoke or for audio files uses WAV format. The output after key change is the same format input.
If the other programs you mentioned can use the BIN/CDG format then they should work without any problem.
I can't answer whether TDK is better than Memorex for you as I only use the Memorex Music CDs myself and have never had a bad burn except for user generated ones.
