Anyone have any issues or data with these units yet?
I saw one of my breaking up yesterday until I stopped it and replayed, it then was gone.

I got this input from Kwon also.

Korean customers are saying that D-VHS VCR's head cannot be cleared by ordinary VHS cleaning tapes.
They are saying that D-VHS cleaning tapes is essential for its use

Just starting to plan ahead.

Usually head clogging happens in two ways-
1. oxide particles and other debris clogging the head gap
2. A glazing buildup, usually caused by metal tape over long periods of time.

The #1 is cleaned by a wet type tape cleaner or better manual cleaning by hand with chamois sticks and 99% IPA.
The #2 is more stubborn and generally requires the use of a cleaning tape designed for this service to abrade off the glazing.

Since DVHS is oxide tape, I would think that wet cleaner only is all that would be needed. Using a dry cleaning tape on an oxide tape machine is never recommended even though these are available. Conversely, using a wet cleaning process has limited effectiveness on a metal baseed machine and the dry tape is recomended.

There is also the lubricant incompatibility issue that happens when mixing tape brands that has been known to gum up the heads. This can be serious and the recommendation is to not mix tape brands. I have only heard of this issue with DVCPRO and DVCAM machines meaning that Panasonic brand tape is incompatible with the others.
