Query: Cannot use universal remote

The remote control that comes with this unit is the only one that we can get to work with the unit. Since there are only play/pause, eject, record, and standby/on controls on the front of the unit, if you lose the OEM remote you can no longer navigate menus or skip ahead/back. This is constantly a real pain in our family since we habitually lose the small remote that came with the unit and cannot use the other three universal remotes to control it.Also, we have had problems recording DVDs - sometimes it messes up during formatting the disk and leaves in unusable -- sometimes we record a disc-full of programs only to find that they are unplayable later.
