It's not, as the card needs to be inserted in a slot. At the end of the 
number of available slots, you need a new motherboard or something to 
get additional slots...

This can be solved with a dual capture cards like the pvr500, however, 
there is always one program more to capture...

Fortunately myth can handle more backends so in the end there can be a 
capure card for every channel to record.

Finally there is always the wish to capture the next program.

I have not read the thread (5 pages is to much to do in a lunchbreak).

There can be various ways to implement it. It can be live, which will be 
a pane in the ass. However, it can also be part of  post processing: If 
the recording starts late due to other schedules and they happen to be 
on the same channel, then the last part of the previous recording can be 
added at the front. For a start, this can also be done outside mythtv.
