Comcast DTA w/ ReplayTV vs. HTPC & ATI TV Wondor HD 750

post #1 of 2
Thread Starter 
Can anyone explain why/how I could get my ReplayTV to work with a comcast DTA (using gray's cable with a new IR code) but I cannot receive a signal using Win7, Media Center, with a analog tuner (ati tv wonder, HD 750).

I figured the comcast DTA, converts digital to analog, wouldn't the analog tuner pickup the signal?

I appreciate the help, I just want to start recording TV again and the last thing I want to do is pay an extra $16 p/month for a measly recording service.

ReplayTV is the best, I want to get my machine running again (probably have a power issue), maybe I should go fishing for extra parts, I could move my relatively new hard drive and motherboard into a "working" device.

I would guess that Comcast is encrypting the digital signals and the ATI TV Wonder 750 can only tune in ClearQAM channels. If you want to watch the digital cable on your HTPC, you'll either need to find a way to feed the signal from your DTA into your HTPC (real kludge, you'd have to change the channels all the time), or pick up one of the new CableCard tuners (Ceton InfiniTV, SiliconDust HDHomeRun Prime, Hauppauge WinTV-DCR-2650).

The Hauppauge can be purchased for $100 currently, and you should be able to lease the CableCard from Comcast for about $2-$6 per month. I'd recommend heading over to the Home Theater PC forum for more information.
