I just got a new video camera. It has the option to record to a mini DVD or an SD card. I didn't want to use the mini DVD since it only records 20 mins on high quality. When I record video to the SD card, the camera limits video quality to the lowest setting. Is this common for cameras that record to a SD card? Is there a better option out there? Are mini DV tapes any good? I want to be able to import to my mac for editing and DVD burning. Thanks!
