[mythtv] [BUG] mythvideo list view parental

[Steven]

Hi,

2 things I noticed. The incparental and decparental keys don't work in 
the listview. They work fine in gallery and browse mode.

Listview on my remote frontend shows all files, no-matter their parental 
levels. On my combined front/backend, with exactly the same myth and 
mythvideo version and the same  VideoDefaultParentalLevel on both, the 
parental level is respected (but I can't change the parentel level in 
listview on either)
