I do have the same issue, Topaz 5.3.3 is reading 60000 fps on my original dv-footage which is 25fps PAL (50i interlaced) and I also don’t want to use telecine process for 23,976 and want to keep 25fps.
Try converting the video file to an H264 codec file and this should clear the tag that is being misread when coming in to the app. I would recommend using VLC Player as its pretty quick on the conversion process.
