Just as an FYI, TCM-HD uses mostly SD upconverts and not HD Masters. The PQ is not bad, but it's not HD. This was discussed in a TCM thread below, as well as several other blogs. TCM is slowly adding HD quality movies to their repertoire.
TCM & HD Masters
And yes, I know that movies are telecined, etc. The TCM issue is unique and eventually they will be showing HD quality movies. If you wish to discuss this topic, please use the existing TCM thread and don't take this thread off topic. Thanks.
