I recently upgraded to a 4 tuner TiVo Premiere XL4. I called Comcast and they told my my current 3 year old Multistream card is only good for 2 tuners. They scheduled a technician to come by. The technician told me that 4 stream Mcards are not available in my area (I live on the Eastern Shore of MD). He gave me his supervisor's telephone and told me to calll every few months or so to see about availability. Anybody had this problem? If I complain hard enough shouldn't they be able to get one sent in from another area? Thanks in advance for any input.
