New AVT-8710 ghosting problems
 

I've bought 2 unit (AVT 8710) from B&H 2 months ago, i'm having big issue with ghosting on both unit. I can't trust them to transfer VHS. It's ok with HI8 transfer, absolutely horrible with my Sony EIAJ AV-3600.

I've bought a used TVOne 1T-TBC-GL, done a quit test today, seems to have the same ghosting with a VHS.

What should I do with both AVT-8710 from B&H ?

I'll be back on my TBC-3000 as I don't have ghosting problem... (bit of shift in the picture and brightness fluctuation, that's why I was looking for new TBCs)

Thanks for the help.

Just return them, and use DataVideo TBCs instead. Cypress changed something in 2011, and obviously has no intention to fix it.
FYI: TVOne and AVToolbox are just rebadges of Cypress Technology TBCs.

B&H won't take the AVTs back because it's been 2-3 months that I bought them. If I contact AV Toolbox, they will exchange under warranty (I guess, maybe, they will probably say that there's nothing wrong with the unit ?), and send me units that will have the same issue.

I guess that my only choice is sell them on ebay and loose money ?

Chat with AV Toolbox :

I just purchased the same unit, and while I'm not a professional by any means, I don't see any ghosting issues. Can you throw up an example so I can see the issue you are observing?

Two baddies in a row? Unusual, but there are indeed QC issues with the newer AVT's. BetaMax, though should be usually be capped using composite, not s-video.

I assume you tried a capture without the TBC's in circuit? For VHS you mostly need a line level tbc, not a frame tbc -- unless they're copy protected.

No, that's not accurate. :no2:

The line TBC is for cleaning the image of timing error.

The frame sync TBC is for non-visual stabilization of the signal, so that digital capture devices can lock onto it. It has nothing to do with copy protection, aside from the fact that "copy protection" is simply an artificial signal error. The frame sync TBC removes all signal errors, both natural and artificial. Without a frame sync TBC, it will still have issues, especially dropped frames.

I don't have them anymore. I also got some ghosting and herringbone with the TVOne Task 1T-TBC-GL (same manufacturer).

I've got the same result. This link is from the page #3 of this post : http://www.digitalfaq.com/forum/vcr-...-8710-doa.html

Yep, I get that and you're right (as usual). I'm just saying take the external tbc out of circuit to compare results without it. But I'm also assuming this was already tried.
