Changing the scanning mode
• 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 JPEG/MPEG-1/MPEG-2/ASF file in 
the progressive scanning mode. In such a case, 
change the scanning mode to “PAL” or “NTSC.”
• All JVC progressive TVs and High-Definition TVs 
are fully compatible with this system.
