How much recording time do I get on an 8 GB card?

Also can I switch out 8 GB cards for memory card A but use a 32 and continue recording for memory card B?

Sorry just saw this. The easy answer is you can mix and match cards in the SD slots. 64 in A, 32 in B, etc. As far as recording time, it will depend on the card size, as you probably knew, but also the quality setting (FXP, MXP, etc). Here is the chart from the G10, but the G20 and 30 are all the same.
