Having two major problems with my vx2100, every time I insert a tape and have it on 'save' mode, it says on the lcd screen that the tape is unavailable, but the rec one is fine to use. Another thing is that when I press record, the tape counter on the top right will begin recording from 0, but as soon as I end the recording, the tape counter will reset and I won't be able to review the footage in VCR mode, any solutions?
