Need help in copying DVD-5

If the content can fit in a DVD+R disc, there no need to do the ReMPEG process. I think the file you rip does not contain all the file need, so go throught the file once and make sure it contain: VIDEO_TS.BUP VIDEO_TS.IFO VTS_01_0.BUP VTS_01_0.IFO and all other VTS_01_X.VOB before you drapped to Nero to process the burn. If it does not contain all the file, you can used Ifo-edit to creat the new files, used VOB_Extras/Creat New Ifos before you burn.
