Question

This is a brand new 'jazz hdv178'. I inserted a 8GB SDHC card, formatted it and I get just over 2 minutes of video recording. I can upload the recording and it all works well except for the recording time. The camera gives no indication it recognizes the SDHC card when I insert it, the lock is off.

Is the SDHC card compatible or should I use a SD card?
