Once you press your instant replay button, VDR would start replaying the
stream from the beginning of the buffered data. At the same time VDR
would start recording the live stream to a file and you would be using
two cards. 

I agree with you that it would be more elegant to buffer the stream
while watching with a single card, but eventually you would need the
second card anyhow, otherwise you would loose that part of the stream
that you missed when watching the instant replay.
