[QUOTE="morpheus_xx, post: 1186005, member: 48495"] This is not that easy: If process runs in x64 mode (AnyCPU), you will fail to load pure x86 assemblies. If assemblies are also AnyCPU it works fine of course. But this is only the minor issue in the .NET world. All other unmanaged dlls need to be available in 64 bit as well (and there a few used in MP1/2). If such a dll is available in 64bit, you still make sure that P/Invoke calls use correct marshalling settings (i.e. pointer sizes are different). Last but not least, the whole DirectShow chain (Source Filter, Video Decoders, Renderers) need to be available as x64 as well. I did some tests before with MP2 but already stumbled upon multiple missing libraries for x64. For regular GUI rendering etc. I don't expect any advantages to switch to x64 (i.e. considering some data structures are bigger). Maybe the video decoding would be more performant, but only in software decoding mode (HW decoders are probably not affected in performance terms). For server process (MP2-Server/ TvService) it would also mean to have TV card / drivers / filter support for x64 as well, which I expect to be not always the case. [/QUOTE]
