Calling all Experts! Just digged, clips on timeline stuttery then error. First for me

Hello everyone,

Im not a newbie in editing. I do my research as well. However, I am encountering a problem for the very first time. I digitized some footage shot on the sony hvr-z1u in 1080i 60i. My project format 1080i 59.94. threw some clips on the timeline and playback is a no go only audio. Seems I get this red render line on the bottom as well. I ususally always have experience in cutting p2 footage. so I dont know what is wrong. A quick help or guidance will be greatly appreciative for this hard working gal. :).

Thank you in advance.
