Just more proof that this is a PP2 related issue.

Thanks for all the work, Tim. I'm certainly happier for the problem to be a bad batch of tapes or dirty heads than some big problem with the camera.

I do have some new JVC ProHD tapes on the way. I'll also get a head cleaning tape.

Why do you suppose the JVC engineers said it was the ccds? Did they figure just send out a replacement and keep the customers from complaining?

Also, my camera was fairly new for dirty heads, I thought. You're saying it's just a case of dirt, gunk whatever gets in there?

Not sure about that Tim. The new tape from the new cam showed nothing but beautiful but shakey footage. Also captured in PP2. It may have been the tape, might have been crud on the heads. Thing is, I don't know what it was, which is why I came here and asked "what is red and about 9 frames?" So far, there is no frame dropping/corrupted image, and best of all, no red!

No insult intended J.J. ;)

I don't know how they came up with CCDs. It just seems so far-fetched.

This issue has been brought to the attention of some top people at JVC. I received an email recently from Robert Mueller with a suggestion from JVC's Product Engineering Manager that the problem was probably "gross data corruption including loss of motion vectors, possibly caused by head contamination." He also mentioned that "When properly operated, the HD100 monitors data integrity ... While the GY-HD100U is no more sensitive to head contamination than other commercially available DV and HDV products, the symptoms of MPEG2 data corruption are quite different than DV errors." That's the official response.

Who knows if we will ever really find out if there was anything actually wrong with Keith's camera, but considering there are now four people who say they've seen red frames when using PP2, it seems PP2 is not friendly with dropouts.

Dennis, if you still haven't sent your camera back I'd love you to run a head cleaning cycle, use only ProHD tape, and see what happens.

The bottom line for Keith and Dennis is that you are getting brand cameras via a great dealer like Texas Tapeworks, and you will both be happy.

Tim,
What brand of head cleaning tape would you recommend?

I imagine JVC has its own brand.

Thanks

Andrew

Drew- JVC has it's own ProHD tapes, at about $10 a pop.

Tim- as I mentioned else where, Dennis' camera and mine, are to be disected, so that they can find out what went wrong... went wrong... went wrong...

We're going to be test subjects!

Where the hideous truth will be discovered... the JVC GY HD100UA is made of PEOPLE!!

Unfortunately, my camera is already back at the dealers. Weren't there some other folks who got this?
