There are reasons Server 2003 is not supported and one of them (that is possibly related to your problem) is the DVB bug that exists in both WinXP and Server 2003. Microsoft has published a fix for XP MCE (which essentially is XP with the additional MCE app installed) but NOT for Server 2003. Since XP and Server 2003 are quite different (there are significant differences in both API and the Kernel) this fix is not appropriate for Server 2003 even if it seems to be working (and your issue may actually be a result of this as the fix is related to tuning). And since we cannot know in advance if it is an OS issue or a TVServer issue, it is a pure waste of (our limited) time to try to figure out what is wrong, only to end up discovering it is the OS at fault.
Sorry if I sound a bit harsh, but to me a non-server OS that has a working TV subsystem is far more suitable for running TVServer than a server OS that has issues with TV.
