Hi,

If I get a device with HDMi output, is there anything on the market (even as a kit I could build)
to connect it to standard A/V inputs on a DVD recorder ?

Thanks, Kirk




Cheers - Kirk

There is many on DX, I had one for a while so I could use the mysky inbuilt composite out for 4:3 and then the one on the HDMI out to composite for 16:9, gave it to a friend to put into their modulator from a hdmi split on their home theater, but ended up with audio sync issues between the displays so they never really use it.

I think you need a HDMI to composite converter. check them out on amazon.

Just about any device you might want to buy should have standard composite output (3 x RCA: red, white, yellow).  And certainly any DVD recorder you might have will have standard composite input - basically because that's the lowest resolution that the media owners are happy for us to record to on DVD.  So all you should need to connect your two devices is a standard analogue composite cable.  Unless there's something you haven't told us?

Thanks for all the responces. Rich is that sync problem with one of the 2 units at Jaycar?

Understood Y-R-W RCA is standard, but if HDMi only I'd need one of those.

No the sync issue is because something happens between the reciever and the TV to sort out the audio delay to match the TV and it isnt appropriate for the output from the HDMI to composite converter. Not one of the jaycar ones because they are about 4x the price of DX or ebay

Buying a converter to send HDMI to a DVD recorder's S-video-in or composite-in would almost be like a Rube Goldberg setup. If recording from HDMI is what you need to do, then something like the Hauppauge Colossus or an HDMI to component converter connected to the Hauppauge HD PVR would be a better option.

The HDMI to component converter on Jaycar's specifications only lists support for 60Hz HD modes. There is a cheaper one on Amazon called the "ViewHD" that looks superior, assuming it supports 50Hz.

If you consider the Colossus as an option then don't forget that it doesn't support HDCP inputs, therefore if you had an output stream with HDCP you would need to find some means to "un-HDCP" it.

I got a box to fix hdcp off ebay. problem is it "upconverts" to 1080p and does it really badly and messes up the colour.

Thanks again for all the info and advice. Looks like it's not that straighforward. I don't even know what HDCP is - yet!  Or is it High Definition Copy Protection ? If so, I did wonder if converting it would somehow get rid of all that stuff.

HDCP can only exist on digital connections like HDMI or DVI so converting to YPbPr or VGA removes the HDCP. There are devices that can record in HD from YPbPr like the Hauppage HD PVR. But while making a HD digital recording from a HDCPed HDMI source may be technically possible, I'm not aware of anything that does that short of some of the equipment a TV station would buy.

The HDFury3 is an alternative to the ViewHD. There are only a few HDCP-enabled digital to analogue converters that work properly.

There aren't many devices that can capture HD from VGA.
