Hi, I'm using a 20'' imac 05, well every time i transfer video from imovieHD to idvd i get a tiny flashing pixel on the screen when the burnt dvd is playing, whether its on the mac screen or the tv screen the flashing pixel is there. Originally I thought it might be the new hdv camcorder i bought but the flashing pixel does not show in the imovie window nor does it show when i transfer video from imovie back to the camcorder, nor does the pixel flash when i connect the cam directly to the tv to view footage. I only see the flashing pixel on the idvd exported dvd. So i figure it may be my idvd software and not the hdv cam?...what ya think? Anybody else encounter something like this? Thanks in advance for any advice
