• There are some progressive TVs and High-Definition TVs that are 

not fully compatible with this system, resulting in an unnatural 
picture when playing back a DVD VIDEO in the progressive scan 
mode. In such a case, change the scan mode to the interlace mode. 
To check the compatibility of your TV, contact your local JVC 
customer service center.

• All JVC progressive TVs and High-Definition TVs are fully 

compatible with this system.
