Do a search here for HDCP.  Some boxes don't output on other outputs when HDMI is used.  Unplug the HDMI and see if it works..

Slinging Tivo Series 2, Tivo HD, and TW cable from a Pro. Slinging Tivo HD from a Solo, Slinging Humax DRT800, and TW cable from a Classic to Sprint Mogul, AT&T SX66, N62, 8525, and Dell Inspiron 8600 with Sprint EVDO over Windstream DSL.

Hi,

Try playing around with the video settings of your TiVo,  

I got lucky at 576p, was getting the no video at other resolutions (on Solo and Pro), I got the hint from Sling Support, they got it right,

My other resolutions didn't work on component

Hope it helps, tak care

Sorry for the confusion, since HD was mentioned, I thought we were talking about a Solo or Pro with HD Connect,

Since you have an A/V, you should be using either a composite or an s video,

You shouldn't be having issues with HDCP / HDMI / output resolutions (480, 720, 1080), since you're using the composite or s video out from your TiVo,

I'd reset the A/V, maybe try to change the s video cable (or composite, but in rare cases the cables are defective), and rerun setup from scratch (maybe even reinstalling Slingplayer software), making sure cables are well plugged in (including ethernet), etc,

It's weird you're not getting an image with composite or s video (view that they are not HD, and shouldn't get the component / hdmi HDCP eventual aspect), and maybe try another STB (just to make sure it's not the TiVo) if you have another one

What they told you at support, " he told me that I need to connect my Tivo to my TV with component cables not HDMI cables" might be right in some cases, in the sense they want you to 'pass through' your Sling box with those cables, which you are not, since you have an A/V (you still can pass through the composite or s video on your A/V, which you don't need, as far as I understood you are connecting to your TV with HDMI)

" I'll probably keep my HD DTivo since I have a lifetime subscription. ", you should be able to pass your subscription to a new STB/Tivo, according to them

Hope you'll be able to solve! take care

You should be able to change the output resolution from 1080i to 480i while streaming with the slingbox by "pressing" the Up Arrow on your slingRemote.  That is what I had to do if I forgot the change the resolution to 480i before I left the house.  If I recall, you have to press the Up Arrow twice.  The first time just displays the current resolution and the 2nd time actually changes the resolution.

Once you launch the Slingplayer and begin streaming the output from the source device (DirecTV HD Tivo, in this case), you will have control of the device using the on-screen SlingRemote and some keyboard shortcuts.  If you leave the Tivo in the 1080i mode, you will not be able to see any video on your computer, but you will still have control of the device (you should still be able to hear the audio from the HD Tivo w/o video).  Simply "press" the up-arrow on the slingremote, which is the button above the SELECT key with the arrow that is pointing UP (the cursor UP button on the keyboard will work also).  As I said before, I think you have to press the button twice before it will begin cycling.  If the resolution does not cycle through the ones you have selected, then there may be something displayed on the screen such as the program guide or the info banner (the up arrow toggle only works if there is nothing displayed on the screen).  If you think this might be the case, simply "press" the EXIT button and then try the Up arrow toggle again.

You may want to try some of these tips in front of the TV and HD Tivo with the original remote and the slingplayer running on your home network so that you make sure that everything is set-up correctly before you try it remotely and get frustrated if something goes wrong.

Am happy you finally got some image,

I don't remember the TiVo remote controls (but I think there is one to change aspect ratio kind of quickly), had to give back mine as I couldn't get cablecards from my cable provider

What Bbraune is suggesting is a good idea, test / check at home by using the remote of the Slingplayer, you should be getting a virtual one that looks like the real one,

Or you'll have to remember every time to lower resolution before remote viewing,

Am ok with your hook up, don't want to get over complicated, I think it's still weird you're getting no video signal with other resolutions, since you are using svideo and rca, shouldn't influence; as the weak spot on some Set Top Boxes (STBs) is using both component (to Slingbox i.e.) and HDMI (to TV),

Don't know about the DirectTivo boxes, so can't be specific / of help, sorry..., I'd say a recent one, but it seems recent STBs with TiVo are giving the component / HDMI hickup for Sling users (eventhough I didn't have problems - apart resolution - with the TiVo I had, with the double hook up), or at least in some cases
