Hello can I post this here?

Hello.playback problem w/ shrink vs xcopy xpress - Can anybody tell me why when I play back a copy on my home dvd player made w/ dvd shrink it sometimes pauses but the same movie on the same media made w/ dvdxcopy xpress plays back just fine. All settings and variables on my pc are the same. The only difference being that my version of xpress will copy only the movie as w/ dvd shrink I'm copying the entire disc. I use deep analysis and nero. I'm just about to the point where I'll use dvd shrink only when the movie is a double sided dvd and use xpress for everything else. Thanks in advance. Any advice will be appreciated.Rig #1 Asus Rampage Formula Mobo, Intel Core2Quad Q9450 CPU @ 3.55ghz, 2gb Corsair DDR2 1066 Dominator Ram @ 5-5-5-15, TR Ultra 120 Extreme w/ Scythe 9 blade 110 cfm 120mm Fan HSF, HIS Radeon 512mb HD3850 IceQ TurboX GPU, Corsair 620HX P/S, CM Stacker 830 Evo Case, Rig #2 Asus P5W DH Deluxe Mobo, Intel C2D E6600 CPU @ 3.6ghz, 2gb Corsair XMS2 DDR2 800 Ram @ 4-4-4-12-2t, Zalman CNPS9500LED HSF, Sapphire Radeon X850XT PE GPU, Corsair 620HX P/S, Cooler Master Mystique Case, Viewsonic 20.1" Widescreen Digital LCD Monitor, Klipsch Promedia Ultra 5.1 THX Desktop Speakers,
