Page 1 of "no disk" error with remote hacked phillips 890

hi there.
about a year ago i managed to succesfully remote hack the philips 890 dvd recorder using the 750 hack and a one4all remote.
recently i have been experiencing some strange happenings with the recorder when trying to play region one discs.
totally randomly it will display the error message "no disk" when inserting a region one disk.
if i take the disk out and then re-insert it it will then "sometimes" proceed to play.
i`ve tried cleaning the laser with a dvd laser cleaning disk several times but still having the same problem.
like i say though,this is totally random and only appears to be hapening with region one disks.is it the recorder finally getting confused or summit and if so does anyone out there no a solution to fix it???
any help would be greatly appreciated as it`s now out of warranty.
many thanks in advance.
