Heres the test cases I made after that cCiHandler fix:

Live    | Recording     | Play      | Recording   | Live        |
        |               |           | distortions | distortions |
--------------------------------------------------------------------
TV1000  | none          | none      | none        | none        |
TV1000  | TV1000        | none      | none        | none        |
TV1000  | TV1000        | TV1000    | yes         | (1          | (2
TV1000  | TV1000 action | none      | yes         | none        | (3

(1 when card is in replay mode, not possible(?)
(2 switched from live to play mode, still recording at background
(3 every channel switch caused distortions in recording, tested with
many channels from same transponder.

These are the cases that I could think of, did I miss someone?
I hope that ascii table dont get messed up and this clears things up :)
