I can't see why it would not be able to read it if it was burned at 52x. It would just not be able to read it any faster than 48x. This would be a hardly noticeable speed difference. For most reading tasks drives don't use there full reading potential anyway. But really the only way to be sure it to try it out.
ps. You posted this question in the wrong forum. This forum is for discussions on the actual forum itself. Maybe a mod or admin can move it to the "Blank Media" or "Optical Drives (CD and DVD Burners, etc.) Forum".
