I came across five VR6460's that did not play thin tape. They were all within the first year warranty, and had worn head tips too. A replacement upper drum cleared all the problems, but a check of back tension showed that they seemed to be set 'high' from new.

With regards to SVHS tape that was of higher spec than standard VHS. I used it a few times on standard machines, there was a noticeable improvement in picture quality.

The Grundig V2X4 super machines had grooveless upper drums, and yet the VR2020/22/23 all had groves. The tape would have been the same across the system. Grundig must have thought that the tape friction to be so low it didn't warrant the horizontal grooves. Philips must have thought different!

Regards, SJM.
