I recently bought Premeir Elements 8 and a Cannon HV40. However i'm having real trouble transfering my footage from my camera to Premeir. I have been filming on standard Sony DV tapes but my camera is HD, is it these two different formats that are causing the problem?

I have tried playing with different settings in both Premeir and on my camera but nothing seems to work. The footage just won't capture properly. Any suggestions?
