i just purchased a new camera (dvc30 to be exact) on my older camera i used many diff brands of tapes and i heard this wasnt good for the camera. is it true? should you use the same brand of tape from the start when purchasing a camera? also would it matter what brand? i have a dozen TDK tapes left soo if it doesnt matter i was gunna use these and just stick w/ this brand for the new camera... just wanted some other peoples input because a freind of mine had used diff brands of tapes with his digital 8 and it messed up the head
