I've been fiddling with vmware, the receiver install fine and starts normally.
My other hardware, a common interface decryption module installs fine too.
Without the CI module I was able to watch the free to air channels in the vmware machine without jitter, with virtualbox there was a lot more stutter and jitter in playback.
With the CI module connected my receiver software does not start well, it hangs on startup. Possibly this is caused by the virtual USB connection, which is too bad since basically it means I cannot use my complete setup (paytv channels are the better ones of course)
My conclusion is that vmware is definitely the better one for video playback, just thought it would be nice to know
