You need to have CineWave RT Pro installed for realtime DV playback in a CineWave timeline.
If you have the Pro version and you're seeing some stuttering on the NTSC playback, ensure that your DV footage has been placed correctly by CineWave. Insert your clip into your CineWave timeline. Then double click that clip back into Viewer. Check the "Center" setting. It should read 0,1. If it reads 0,0, change the second setting to 1.
CineWave is supposed to automatically place the DV footage for at 0,1 setting. From time to time, it will put it at 0,0 which gives you stuttering and badly interlaced looking footage.
Also, sometimes when I hit play, the DV footage will stutter a bit, even if it's placed correctly. Just stop playback and start again.
