Pioneer DVR issue

I had to reformat (XX!@@##) and now my Pioneer DVR 107D doesn’t work right. Since I don’t know JACK!, I don’t have a clue what to do! When I put in a disc, sometimes it recognizes it and sometimes it doesn’t. In XP, I checked the device MGR and it shows everything normal and it says it has the most current driver. I tried uninstalling and reinstalling but nothing works. ANy suggestions? HAIRPULLINGIDIOT, Thanks
