After learning on its website that the Grex was supposed to preserve closed captions, I ordered one to use in backing up my copy-protected "mouseland" VHS tapes. To my disappointment, I have found that its preservation of closed captions is less than perfect. In two out of three attempts so far, there are numerous missing words and letters in the closed caption output from the Grex. It looks as if passing the video signal through the Grex weakens the closed caption component of the signal, causing parts of the captions to drop out and become unreadable.
I have no doubt that the Grex is the culprit. When I play a copy-protected tape directly from my VCR to my TV, the closed captions are perfect. Also, if I record a non-copy protected VHS from the VCR to the hard disk of my Magnavox 2160 DVDR and then play that recording on my TV, the closed captions are again perfect. It is only when, for copy-protected VHS, I put the Grex between the VCR and the Mag 2160 that the captions get garbled.
SO... what video stabilizer product would you folks recommend I get that will not garble closed captions by weakening the signal? Apart from the Grex, none of the others I have checked address the issue of closed captions on their websites, so I hope some of you folks have actually tried this on your units.
Thanks for your advice!
