Though I have not tried the JVC tapes, there is a difference in brands of tape stock. I normally use Sony Premium tapes, which have proven to be flawless. I recently did a job with the Panasonic tapes and had a horrible experience. One of the 10 tapes shot on the job was bad. How and Why??? I was able to lay down color bars and everything else....???? Who knows. The tape showed only some noise and the time code just kept jumping forward and back. I'll never use Panasonic again!(posted 8624 days ago)
