[QUOTE=MickIL1;2153161]When attempting to record on the DMR-EZ47K from a TWC box 8300HDC this message is displayed on the TV (which is a Sony KDL-52XBR4), Message is in a large yellow display stating “The device DVI Cannot be Used”. But remember I only get this when going through the TWC 8300 box. I have conneted RF cable directly to DVD and it works fine with the exception of not able to record HD and digital programs which must pass through the TWC box. Here are my connections, from TWC box to DVD is S-Video and composite red and white for sound into In1 on DVD, from DVD to TV using HDMI cable. Also fromTWC box to TV is HDMI. I have also used compenent cables from DVD to TV and Composite from DVD to TV, get same message regardless of what type of connections. Have talked to Sony and they claim the problem is not from the TV, which I agree with seeing when I use the RF cable from wall, I don’t get this message display. Have talked to TWC and that is the same as talking to the wall. I’m on my third TWC 8300 HDC box and all were the same. Has anyone else encountered a problem as this?[/QUOTE]
Here is the problem:
You are trying to mix analog and digital connections in your signal path. That S-Video output on your TWC cable box cannot deliver HD or digital signals directly to begin with. In fact, when the digital broadcasts are routed out of your cable box via an S-Video connection, they are automatically downconverted to analog SDTV signals! And if you use HDMI to connect from the DVD recorder to the TV set, the HDMI connection cannot be used at all for digital broadcasts which have already been downconverted to analog to begin with - in fact, that makes the HDMI connection usable only for watching prerecorded DVD videos (the HDMI does not detect a digital broadcast signal at all). To restore viewing from a digital cable box that’s been connected using analog connections, you must also use the analog connections (component, S-Video or composite) to connect the DVD recorder to the TV set. (I see that you also tried this.) If that’s the case, then I also saw that you’re trying to use both digital and analog connections from your TWC cable box to your video devices. Most digital cable boxes I’ve seen cannot output signals in both analog and digital at the same time (which is EXACTLY what your current setup is). To fix this, you must use only the analog S-Video jack, and don’t use HDMI at all from the cable box (most cable boxes automatically disable the HDMI output when an analog output is used). If you want the full HD/digital experience when watching cable programs, then you must disconnect the analog A/V connections from the cable box before you can connect the HDMI connection.
And what makes this situation tough is that there is no current consumer DVD recorder which can record digital broadcasts from a digital cable box directly - the only digital video input on consumer DVD recorders is an IEEE1394 (FireWire) port for use with a camcorder; otherwise, DVD recorders can only record an analog external video source. (Of course DVRs which can record digital cable or satellite broadcasts directly do exist, but such units must be obtained directly from your cable or satellite provider directly, at an additional monthly charge - and then, you may face DRM issues such as the inability to play back your digital broadcast recordings on anything besides the DVR that you made such recordings on without the need for a digital-to-analog step.)
