Well got the TivoHD last week and hooked up using Comcast analog just to try it out. Worked Great ! Was kind of annoying having the HD channels listed as 5-1, 2-1 etc... but they looked great. I knew I wanted the cable cards so I read up on them here on the forum and began my journey. 1. Called Comcast 800 # to ask about picking up one M-card from my local office. "What is that" she said. Oh boy. Finally spoke to another team member, came back to the phone and said that i could pick up the cards at the Schaumburg office Yippee ! 2. Drove 30 minutes to the schaumburg office. "We don't give those out here". Sh*t!! "but the lady on the phone said...." They didn't care. 3. Read a post here on the forum that mentioned the North Ave. office was handing out the m-cards. I drove down 45 minutes to the office sat. morning and there was a HUGE line. While standing in line I called one of the agents over and to verify that they did infact hand out cable cards, he said "no problem, we give them out here". 4. After waiting in line for 40 minutes I got to the window and the the agent grabbed the card from the back. BUT the stupid computer wouldn't let him assign it to my account, because I lived int he suburbs and this office was in chicago proper and he refused to hand it to me!!! Crap !! 5. Called comcast to schedule an appt. 6. Monday 2 guys showd up with 15 freaking cable cards. The said "These freaking things never work". After 30 minutes of back and forth on the phone everything was working..or so I thought. Before they left we testing some channels..but unfortunately (stupid me) we only tested channels 9 and 191...later found out that all channels above 20 didn't come in except for the last few HD channels 187 - 193? 7. Called comcast, they "sent a signal" to my box. Didn't help. they then "Sent a stronger signal" I don't know if that is BS or what, I guess it sounded better then having the lady say "sh*t I ain't got no clue why it no workie, let me keep trying the same thing over and over"...well the "stronger" or 2nd attempt worked ! Hurray...everything is working great with m-card in slot 1. Finally.
