I typed in all the track names and album name, checked the CD text box in the burn dialog - but no CD text showed up in the burned disc. Using 5.2a. Any suggestions?
You don't say how you are attempting to view the CDText on the burned disc.
Not all players will read CDText and if you are using one of these then you will not be able to see the CDText even if it is there. In particular, Windows Media Player will not read CDText.
If I recall correctly the VLC player will display CDText. You can find it here.
But if you just want to check that the CDText information has been recorded correctly you can just read the information back from the CD using CDArchitect.
