Yesterday I received a miniSD 4gig card I ordered from
www.flashmemorycard.com for $48.95.
I copied everything from my 2gig card to desktop using a card reader and then copied from desktop to the 4gig card.
Everything seems to be working just fine on my Hw6945. I only have a little over 1 gig of data loaded now. It will be interesting when I go over the 2gig barrier on this card.
I have seen the 4gig miniSD card on other sites.
But you must be very careful. Do NOT get one where the description says SDHC or meets SDA 2.0 specs.
The card should be printed with miniSD - NOT miniSDHC.
Hope this helps.

I loaded up the card with some movies to push it over 2gig. Then I added one more. Everything seemed to play ok.
