I just purchased a used TiVO BOLT VOX (Antenna and Cable) Model TCD849500V. I live in an apartment complex and our digital cable channels are decoded before the signal enters the apartment. In other words, I do not use a set top box to get my basic digital cable channels (which is all I'm concerned about). Our cable company is CTC (goctc.com) and I live in Baxter, MN 56401. I ran the setup as Antenna to see if it would identify the digital channels and it seems it did without a problem in the channel listings however I get no picture. CTC does not offer a CableCard. Just wondering if there are any work arounds or genetic cable cards that might make this work?
