Anyone have any experience with mlb.tv on the Roku? I've got to decide soon if I want to stick with the package on Directv or go with mlb.tv. Also have a Smartv with mlb.tv app on it. Anyone with experience that way? The price difference is negligible if you haggle with Dtv, but from what I've read, mlb.tv has a few more perks you don't get eith Dtv. Archives, etc. Appreciate any thoughts.
