I just had fios installed and trying to have one of the boxes going to my computer so that I could watch tv from the computer as well. I have a hauppauge wintv-hvr 950Q tuner which used to work with my old cable box (optimum). The new cable box is an aris IPC4100. just looking to find out if there a way to get it to work, or if anyone knows of a newer tuner card that might work.
Put a splitter inline with the coax going to the 4100 box. Hook 1 coax to the box, the other to your tuner card. Scan for channel channels. You wont be able to get premiums like HBO, but you should see a bunch. To get the premiums you paid for you have to go to the Fios app, or My Fios and watch tv.
