Is your source progressive or interlaced? And do you plan to play this video on computers or TV? If it's destined for television, then interlaced video is common and the Blu-Ray player will know exactly what to do with it. If it's destined for computer playback, then you may have a problem.
But you've given nearly no details for anyone to even begin to help you.
yes, it's 60i and going to blue ray, for tv...computer playback show's interlacing/mice teeth and wasn't sure if blue ray knew how to handle it....figured best to check before i burn an expensive disc.
So you are playing interlaced MPEG-2 on a computer? Get a player/codec that is capable of deinterlacing.
Why do you export in MPEG-2 instead of AVC? With AVC you can have lower bitrate with the same quality, and you can make a complaint AVCHD disk on DVD media and check it on your Blu-ray player.
