I just purchased a new laptop running windows 7 home premium. I've downloaded codec Media Player Codec Pack 4.1.7 and Windows 7 Codec Pack 3.9.0. Installation seemed to go just fine. It will not play any VOB files from any source. I have another laptop running the same OS, same codec packs and it is playing the same VOB files just fine that the new laptop will not play. What settings could I check that might be blocking these files from playing. I have tried to play ISO files and they play just fine, but not VOB's.
