Video Object (VOB) files are the native video container format used on DVDs. Windows Media Video (WMV) files are one of the video container formats supported by Windows Media Player and several other applications. Converting between the two formats is routine, and there are dozens of utilities that can do it. Early versions of these programs would run into problems with very large VOB files, and would fail on the conversion part way through. This conversion limitation was the result of maximum file size limitations in Windows 95 and other 16-bit operating systems. Current conversion utilities, as of February 2014, no longer have this problem.
