Today, there is no doubt that YouTube is one of the most challenging services in current wireless networks, and that the users' satisfaction expressed via QoE metrics is within the main interest of the network operators. As a result, the research effort focused on QoE assessment and modeling is constantly growing. Being one of the latest standardization activities in this domain, the ITU-T P.1201 recommendation addresses the quality predictions of TCP-based, non-adaptive streaming typically referred to as progressive download. In order to evaluate the applicability of this standard for YouTube service operating over the state-of-the-art mobile networks, we conducted an initial performance analysis of this standard while comparing it with real outputs from other previously implemented QoE studies. Our findings provided in this paper include the practical drawbacks of the P.1201 specification.
