I have two DVD plaier programs on my PC. One is DVD Station that came with the RealMagic Hollywood Plus card. I also have PowerDVD, but both of these play certain burned DVD/VCD and certain Mpeg files upsidedown and backwards. I thought it may be a conflict with the codecs, so I uninstalled the Nimo codec pack, and no result... However, while I have the Nimo pack installed, all the mpeg files and VCDs will play in Media Player correctly. What is it with the DVD software?
