Came home from a OSU/ Michigan Party today.. I had recorded the game on the HR20. I started to play the last quarter and the screen went blank for the rest of the game. I started to look at HD channels and they came up for a few seconds, got the banner and no picture. Same with the SD channels. After several calls to DTV they are shipping a new receiver next week. Does this seem normal for folks who have lost ther HR20's? Also I notice satelite 99b has no signal... is that normal?
