I am using Liq. 6 and mastered my timeline to DVD. The 43 min video took close to 2h 30m to burn. Now I want to make 50 odd copies and used NERO to do it. No problem BUT: my master has 4 VOB files and play back on my TV DVD without any problems. The copied version stops for a while at the end of the VOB1 file before it carries on and then stops again at the end of VOB2 file. My clients do not like this!! What am I doing WRONG? I am not using any "chapters"
