As another Samsung 841 owner i've experienced the gap between tracks as well. I rember reading a thread not to long ago stating that adding a picture track will fix this problem. So i made a test disc in wavelab, 1 set with a picture track & one without. The set with the picture track did play back seamlessly. The set without a p-track still had a 1-2 sec gap. So if you own a Samsung HD-841/Toshiba 4096 try adding a picture track & see if it doesn't fix the problem. Note DVD-Audiophile doesn't support picture tracks, use Wavelab, discwelder,etc...
