I have a Onkyo3 SR04 hooked up to comcast Motorola cable box and Syntax Olievia 32" LCD TV using component output. When I set up the cable box output as 720p for HD, I have no problem watching HD programs. However, if I switch to 1080i, the screen starts to flicking very often when watching HD, sometimes it will even black out (blue screen) for several seconds. If I connect my cable box directly to my TV with the same component cables, the flicking was gone. Any advice? Thanks

1) Connect the Tivo using the coax output of the cable box into the cable input of the Tivo
2) Exchange cable boxes with your cable provider for one with composite output jacks. It may require you to use a Motorola box that isn't High def depending on what your provider has. I know Comcast has a Motorola HD tuner that has composite outputs as well as component.
3) Upgrade to a Series 3 Tivo. Those units are designed for High Def. Use HDMI cable hookup.
Connect the HDMI outputs on your various components to the HDMI inputs
on your receiver. Connect the HDMI output on the receiver to the input
on your TV. HDMI incorporates digital audio, so no need to buy optical
audio cables. If your receiver does not have HDMI inputs for all your
components, you will need to make a choice. HDMI = Best, component
video + optical audio = second best, S-video+ optical audio = third
I had the same problem
you have to set up the componant on DTV.
the signal my be hd 1080i and the only connection with componant that can support this is the DTV port.
the other componant connections only support 480,
well dvd player is only 480 i ok not 720 unless its blue ray so dont even do that coupont cables usallly 480 also with comcast outs do u have hd then use one with hdmi outs ok coxal digtal cable works great also better rcas
Go the the settings on the cable box. look for output resolution, then change it to 1080i and 720p. now turn the box off and back on your tv will now display the input of wither 1080i or 720p depending on the hd channel your watching.
