I'm not sure if this is a bug or not...
Since around the time of installing X-Select 0.6 I've been having probs accessing the DVDROM contents via FlashFXP.
On accessing D: I would only get the contents of the C: Drive, after much playing around, ie. Refresh, ejecting and so on I couldn't get it to work.
I removed X-Select and made Evox the boot xbe and I could see my DVDROM contents again, just to make sure I put X-Select back again as the boot xbe and again the D: drive was back to displaying as C:
btw I'm using x2lite 4973
