I didn't think there were any SVHS decks without TBC, but then I recalled there were actually less expensive decks that cost a few hundred instead of the $1800 I paid for my AG-1830 SVHS deck back in 1998.
You did adjust the tracking, right? That sounds like it could be your first problem.
Find a post outfit that can do the transfer for you, shouldn't cost much.
Then you would get the TBC and a 4:2:2 transfer to say DVCPRO50 instead of the miserable 4:1:1 (DV25 I presume) through your camcorder.
A post house may also have a deck with better heads that can pick up poor tapes better.
Hi - thanks for replying. Yeah I'm adjusting the tracking - unfortunately these are family videos and there is about 200 hours of footage and I have no budget. I'm not wanting to edit them into anything, just to protect them from tape degradation over time.
