Cheep Mini DV tapes can can be more problematic, however the most important thing about using tapes is to ALWAYS use the same type of tape in your camera. Different tapes will use different types of tape lubricant (dry lubricant, oil based lubricant) If you are switching different types of tapes in and out of your camera then the mixing of the different types of lubricants will cause the heads in the camera to get dirty.
I always surprises me how so many people don’t know this and just grab any old tape they see in the store.
