Anyone know what the status is at TiVo for fixing the CableCARD macro-blocking on both ports? I'm still having tremendous issues on my TivoHD with Scientific Atlanta cablecards on Comcast in southwestern Connecticut. Before the cablecards were installed, I had no issues at all... once they were installed, there has been huge macro-blocking very often (once every minute or more at times on some channels such as my locals and especially HD premiums like TNT-HD/etc.). I really hope this recent patch isn't the end of the fixes, because for me, it did not do anything (I am on the newest version as of this posting according to the system information screen). Anyone spoken with TiVo today and know what's going on? I'm going to call them in the afternoon, but this is infuriating... I have two Tivo HD's and may have to return them if this can't be fixed in a timely manner.
