Just wonder if other people who use the PVHD1000 to record if thier tapes occasionally fade to black and white for a few sec and then return to normal.

I have been expriencing this lately. Is there something wrong with my record head? or is it the tapes I am using (Maxells and Fuji)?

I'm assuming you are talking about recordings made in DVHS mode.

Is this a random occurrence, or does it always happen at the same point on the tape?

It happens at the same spot on the tape. I don't see the B/W when I watch the source. But when I play back my tape of the source it happens at the same spot all the time. So it has something to do with the recording? Would be my guess. Just wondering if anyone has experience the same thing. A colour picture shifting to B/W and then back to colour at the same spot on the tape.

I am using a DST-51A made in october 1999 with my consumer model panny manufactuered in July 1999.

Thanks for your replies

I've never seen this happen on my machines. I would be more suspicious of the DST51 than the HD1000, only because I've seen a similar problem with audio, where a DVHS tape will have no sound when played on one STB but perfect sound on another. Sorry I can't be more specific. It's an area I'm investigating because because a friend of mine has a STB that works with some tapes but not others, but I don't have answers yet.

I think I would try the "reseating" routine I described a while back on this forum.

No guarantees since I've never seen this before.

This very much does sound like a decoder problem and not the VCR. The vcr simply records the MPEG stream. This signal does not have seperated color components in such a way that would produce only B&W information. Any data loss that severe would scramble the entire picture.
