Right now your only option is to configure your system such that LiveTV 
always defaults to the standard-def only cards.  I don't feel like 
describing how, so I'll link you to a completely unrelated post with a 
lot of info on how the LiveTV capture card is chosen with the 
many/various settings and let you figure out the configuration to use.

I personally think that the extra code and settings to allow users to 
specify "this is an underpowered system that can't play back some types 
of video" is not worth the cost of time to implement, test, and 
maintain.  IMHO, any MythTV user should get frontends capable of playing 
the content they have.

But, if you feel like implementing some functionality, feel free to do 
so.  I won't be the one reviewing the patch or deciding whether to 
commit it, so feel free to ask the other devs their thoughts on the 
matter/try to sell the idea to them.
