5. Started timeshifting a different channel from TVserver setup , on a different TV-card (DVB-T). Same result, memory usage starts growing. This time though it seems it does not continue to grow after stopping the timeshifting - but the used memory is not released.
It is perfectly normal that memory is not released when it comes to .NET applications. It is up to the Garbage collector to decide when to free the memory. This makes troubleshooting the memory leaks with TVE3 quite hard since you cannot know so easialy if it is a real leak or just .NET's runtime's garbage collector that has not seen any reason to release the allocated memory.
