Problem with Hi8-video using S-VHS on Leadtek TV2000 Expert

Recently, I bought a Leadtek TV2000 Expert TV-card.
Everything is fine (TV and FM). I started to capture Hi8 video tapes from a SONY Hi8 camcorder (CCD-TVR64E) using a S-VHS cable and the S-VIDEO input possibility. The result was rubbish (hardly visible images or contours, enlarged, black horizontal and vertical bars, mostly red and blue colours). But using the composite cable and with the same settings the result was right. Still I like to capture with the higher resolution S-VIDEO possibility using the Hi8 format. Has this problem to do with the Leadtek card or with the camcorder and how can I cure it ? Thank you for your attention.

 

I have solved the problem. After a long search it turned ou that my newly bought S-VHS cable was defect !
