There are other ways to fix that (don't copy, use shared libraries ...).

Yup. Guess you are just unhappy about the tv apps available for
budget cards?

(1) It doesn't make much sense performance-wise, when passing stuff
using a v4l(2)-like interface to the apps you have to copy the
data way to often.
(2) You lose functionality, being able to just save away the MPEG
stream for example.
(3) Yoo lose important informations, the timestamps for example (which
are really important to get a/v sync right).
