The thread discusses issues with playing videos on Windows, where the original poster (davidhk129) reports that neither Windows Media Player nor VLC could play videos initially. After trying different versions, they found that VLC version 2.1.5 from the official site works. The user also notes that Windows 10 Technical Preview warns against DVD playback with Windows Media Player, questioning why third-party apps like VLC are easily accepted by Windows 10 while built-in options like Windows Media Player are not supported for DVDs. Overall, the sentiment reflects frustration with DVD playback limitations on Windows 10 and confusion over Microsoft's support policies.
