Can you provide downloaded xml file? I'll try to use it in my local http server to simulate what is wrong.found an issue with x64 TV Server and the Schedules Direct plugin. When I installed TV Server 1.33 x64 pre over my 1.32 x 86 TV Server, I had two weeks of guide already scheduled. Now that 2 weeks is up, I realized TV Server was not refreshing SD to keep the TV Guide updated. I had to install 1.33 x86 TV Service to get my SD refresh to refill my Guide.
MP TV Server 1.33 x86 pre is working with Schedules Direct, and showing 2 weeks of TV Guide data in my x64 clients.
