Hook up problem

That is the part that contains the tuner.

Perhaps your TV is not compatible with the new digital signals you now get from your provider. But you should be able to get (buy) a digital receiver from your provider, that is can receive all channels and can be connected to the TV with a HDMI cable.

Could be the HDMI bank, try the DVI hook up, you won't have HD but it would give you knowledge.

HDMI means high definition multimedia interface.

When connected to an HDMI compatible unit, an uncompressed digital audio and video signal is transmitted, enabling you to enjoy high quality digital video and audio with just one cable. When connecting to an HDMIcompatible HDTV, the output can be switched to 1080p, 1080i or 720p HD video.

Panasonic uses Viera link option between their video products.

When connecting with a Panasonic TV (VIERA) or a receiver equipped with 'HDAVI Control' function, linked operations are possible. [Linked Operations with the TV (VIERA LinkTM HDAVI ControlTM)]

Please use HIGH SPEED HDMI cables that have the HDMI logo (as shown on the cover).
It is recommended that you use Panasonic's HDMI cable.
Recommended part number: RP-CDHG10 (1.0 m/3.3 ft.), RP-CDHG15 (1.5 m/4.9 ft.), RP-CDHG20
(2.0 m/6.6 ft.), RP-CDHG30 (3.0 m/9.8 ft.), RP-CDHG50 (5.0 m/16.4 ft.), etc.
Non-HDMI-compliant cables cannot be used.

(the above is from the owner's manual of this model - page 40 tells you about linked operation using HDMI HDAVI control and how to set it up)

As for Gem HD, this unit has an SD (standard definition) digital tuner - it will not decode/receive HD channels. I should point out that 7mate also is a HD channel but is not specified as such in any menu or even their website. (I found this out by accident when I tried to record on timer 7mate one day and all I got was 'unable to decode HD channel' banner at the bottom of a blank screen)

Channel 11 is a SD channel - so this will work with your DMR-EZ48 as will all the other relevant main free to air channels (ABC/7/9/10/SBS). GO! is also a SD channel.

To be able to record HD to this combo unit you will need a HD set top box connected via its AV inputs. HDMI simply means you will get HD video quality from the combo to the TV, you will not receive HD channels from your HDTV to your DMR-EZ48 unit via this method.

You must connect up the TV to the SKY box, via Audio Visual cables too, in order to watch, recorded programs. You need to hook, up, Component, HDMI, or Composite, You select it by an EXTERNAL channel.
Connect the cable running from the wall into the "In" port on the Sky Box HD receiver. This cable brings in the signal to your receiver. Make sure the cable is securely fastened to the receiver, otherwise you might experience image and audio issues.
Attach an HDMI cable into the HDMI port on the Sky Box HDTV receiver. The HDMI is a single cable that provides both HD audio and video signals.
Plug the other end of the HDMI cable into an available HDMI port on the HDTV.
Power on the HDTV and the Sky Box HDTV receiver. Press the "HDMI" button on the TV's remote control. This will display the cable contents of the HD receiver onto the television.

Yes you can split the signal out from the back of the Freesat/HD (not the TV)to the second TV.
Look what outputs are on the Freesat box - the RF (standard cable) output should go to the 2nd TV (TV set to CH3) and the a/v cables,HDMI or DVI cable should go to the new TV - Note:To receive HD the output from the Freesat should be either HDMI,DVI or Composite output (RGB video jacks) with red White for audio. If you have HDMI this is best - it also provides audio.

After trying several ways, we decided the best picture was to run the blue ray (out) directly to the TV (in) with an HDMI and another HDMI from the sat. box(out) to TV(in), then optical audio from TV (out) to receiver (in). This way you don't have to change channels on the reciever when switching from TV to DVD. Remember that HDMI is one cable that supports audio and video. If you are using all Samsung products and want to use one remote, using the Anynet feature, I think it has to be connected with an HDMI. I'm going to try connecting an HDMI too from the reciever to the TV to see if this feature will work. It does with the Blue Ray.

When I hooked up my HD cable box using an HDMI cable, I had to go into the cable screen menus and select HDMI output. You may have to do something similar when using an S-video cable. Your DVD recorder doesn't seem to have an HDMI input, so you'll have to use the S-video or (worst case) composite video (red, white, yellow cords). Your cable box may also be scrambling the signal so that you can't record. That may be why you can record by bypassing the cable box.
