I've recently bought the above VCR to replace my old Panasonic. Although I'm pleased with the quality of recordings, playback of pre-recorded tapes leaves a lot to be desired. Nearly all of my pre - recorded tapes suffer from what seems to be poor tracking, with noise and 'sparklies' in the lower part of the screen. Adjusting the tracking only makes it worse. Incidentally, the tapes play perfectly on my 8 yr old Matsui. Is it possible that the heads (or whatever?) are mis-aligned, and if so, will it be a simple job to adjust by an engineer? The machine is still under warranty. Any suggestions or advice welcome.
