I fixed my ultra yesterday and every time you change channels it's slow to come in. It says autoroll in process every time you change channels. It's probably a 5 to 10 second wait even long on some every time you switch channels.
Jeagar this is a temp fix for the last ecm. There is an issue with the timing. As of yet i have not experienced any freezing. The timing shoudnt be a big issue just wait watch and enjoy.
