Debris
Fingerprints, debris, outgassing, or scratched/blemished discs, while frustrating, are not the only cause of customers having disc issues. If there is dirt/debris/fingerprints, please wipe it off with a dry cloth, etc., and do not play a disc that has warped. It's always a good idea to have a micro-fiber cloth handy as it can be the slightest blemish that can cause mega-frustration. Insuring your discs are clean is the first step when issues are experienced.
Disc Variances
As one of the largest physical media player manufacturers in the world, we have observed that commercial disc playback issues are unfortunately player industry wide. This is primarily due to the variance of quality of disc manufacturers, compliance with specifications, and authoring variances.
Due to the wide range of manufacturers and the authoring process, playback compatibility cannot be guaranteed on all discs. In some cases, some titles may play where other same title discs will not, as discs for each country are different or manufacturing plants are different .
NOTE: BD-R XL and BD-RE XL media cannot be played back.
Region Locked Discs
MAGNETAR players may not be compatible with playback on some discs due to region locked titles. Be sure your disc is for the US region or it may not play.
There are disc specifications that are completely different for each region. Similarly, discs obtained from outside the United States, such as imports, may also have compatibility issues.
Known Disc Manufacturing Issues
Recently, it has been learned that a large number of both DVD and Bluray titles were found to be poorly manufactured and we've seen some customers reporting this as player issues.
It's an unfortunate reality of the medium and we are always working hard to insure playability and compatibility with every title and often work with cooperating studios when customer patterns arise around certain titles.

General Information
A good point of reference is if the player is seeing issues persistently with every disc, not the occasional disc issue. In these cases, we're happy to step in, take a look and make sure your player is operating correctly via our support channels.
In sum, the occasional disc misread, freeze, skip, is a rare and unfortunate nature of the beast. Googling the issue can also help reveal certain tips and tricks and reveal if there are any issues native to certain problem titles or discs.
