I have 2 32GB Sandisk Class 2 cards which work great. Many have reported problems with the newer Class 4 cards.

Always test the cards by recording straight through end to end non stop. If at any point they give an error, return the cards. Sandisk has apparently changed their manufacturing with the cards. Try Transcend Class 6 cards. Always test the cards by recording end to end.

You should really test in HQ (XDCAM) not SP (HDV) mode.
