My husband and I made these to enable people to watch them on their TV or computer; either at home or at work. We are located in Oregon, USA and have been selling them for 2 years with high ratings from customers! They come in Blu-Ray or DVD. A Blu-Ray disk will only play on a Blu-Ray player so be careful when ordering. Free Shipping worldwide. Still only $10US! They will play in any player worldwide. We have never had a return despite selling thousands!
