So I was searching through various results of Windows Vista Media Center and I couldn't find some websites that lets me download this version on Windows 11...I really thought the Media Center from Vista is better than 7.
Happy New Year and welcome to Vista Forums! Sorry, but no one on earth is working on that as far as I know. Vista was never a very popular version of Windows, and using Media Center was never very popular among Vista users. I was one person (and among the last) to use Media Center as a DVR on Vista, so I at least understand your question. The WMC that was included with Vista Home Premium and Ultimate editions was very similar to that of Windows XP Media Center Edition (unless you installed TV Pack 2008, in which case it was very similar to that of Windows 7). There are far more Windows XP diehards than Vista diehards, so you might ask the same question at an XP forum. However, there was a question at MSFN recently about “upgrading” XP to MCE, and no one has replied yet.
If you would be willing to settle for the more recent version of Media Center from Windows 7 (and Windows 8 with Pro Pack), then I would refer you to
The Green Button, where there is a section on “Windows 11 Media Center” that might interest you. It looks like you must create an account and log in to read threads there these days. I was a member there long ago.
If your goal was merely to use a Windows 11 PC to record TV, then I would advise you to look at third-party software that is still supported. If you have an old tuner from the Vista era that you hope to reuse, then confirm that there is a driver update for Windows 10/11. (Some manufacturers have been defunct for many years.) If you have HD channels in Germany, note that the video decoder used by WMC on XP and Vista did not support h.264, much less the latest h.265 (HEVC). For HEVC channels, you should forget about using any version of Media Center unless maybe they make converter boxes. New audio formats could also create problems for WMC. Microsoft is no longer in the business of providing free Electronic Program Guide data. There is a paid service called Schedules Direct (and perhaps others), but their data would not be in Microsoft’s proprietary format. There is a hack called EPG123 that converts Schedules Direct data to MXF format (but
not to the legacy format used in XP MCE and Vista). In contrast, third-party DVR software such as NextPVR has native support for Schedules Direct Data.
Of course younger generations subscribe to streaming services such as Netflix and rarely watch “linear TV” anymore, which is why Microsoft gave up on WMC more than a decade ago.
