Sony's Wet Lube could be the Clogging Culprit!
 

I came across this site...

http://www.philpang.com/tips/minidv_lubricants.html ...and it is claiming that everybody besides Sony is using dry lube now, and that using a Sony tape (and possibly TDK) and then going back to a dry tape is what causes the clogging. If this is true than you should be able to swap tapes as long as you avoid Sony (+ possibly TDK)!

Anybody else hear any of this from any other sources? Can we gather up our knowledge and see if tape problems happened only after using Sony's, and then switching to a dry brand? The last tape I put in my cam was a Sony, and I wasn't worried because before that I swapped all the time. I was just about to order some Panny PQs or Fujis, but now I don't know...

Sony switched to a dry lubricant around 1997.

...so then I take it this site is wrong?

Like so many sites it's pretty as a peach but has some rotten spots.

At the end of his dissertation, this enthusiastic young fellow presents the same recommendation that we've offered here for years: use a head cleaning tape periodically (btw, ignore his directions and follow the tape's instructions...sheesh) and Pick 'n Stick.
