I've never had any quality issues with the 710. I've always considered it a good piece of my setup. Thanks for confirming that for me.
The problem is I can't get the 710 to play nice with a new (used) computer I'm trying to set up. After setting everything up I was able to capture a couple of VHS tapes just fine into
VirtualDub. Then I scrapped the Win10 and installed Win7 (I wanted XP but I already had the Win7 disks so I went with that). After installing everything, I tried capturing some more VHS, but the signal is suddenly not stable. Lots of jitters and framing issues. I've been working on that for a couple days now to no avail. It works fine using an old Honestech VidBox I have, but don't want to use that. I think I've tried everything I can think of from new cables to updated drivers to different VCRs to capturing with different software. Always the same unstable picture. When I plug it into the old Win10 computer it still works like a charm. Quite frustrating.
Perhaps you or someone else can think of something I haven't tried or offer some advice. I really would like to continue using the 710.
btw, Welcome back. I do hope your health issues are on the mend!
