what kind of video is this (is it interlaced)

Hi,
I'd say it is interlaced (99%) but moving this video frame by frame I can see some no-interlaced frames (guitar player head from behind). It was recorded with hauppauge HDPVR, input signal 1080i. I'm still learning about this stuff and that makes me wonder if maybe MTV converted the video in some "wrong" way. Or am I completly wrong and this is interlaced all way long.
Thanks

ps.
During playback you may notice audio being out of sync (mplayer) because I cut a small part from of the whole clip using DGSplit.
