Problem recording of hd tv with cable box from

It could be just that the video heads need cleaning.

VCRs are not digital, yes you can run it into the HDTV, but it is not going ot be HD quality, as you probably know... ususally you can use cable or component cables (red, white, yellow) to connect to the TV. If your VCR has RGB cables, use those.

Yes,If a VCR/DVD recorder.Not just a VCR/DVD player only.

If the vcr has two scarts connect the DVR player to one and select that imput. Watch the program using the the other scart connected to the TV. Press record on the vcr and then start the DVR player going. If it doesn't have two scarts use the front panel jacks to connect the DVR player.
The only time you won't be able to record a program is if somekind of anti-copy system is employed.

As I said in a post to another person, make sure that you're routing the TV signal into or through the VCR. If it's from Cable/Satellite or Digital Converter box, it will simply need to be routed with a coaxial cable, it's a simple fiberoptic cable with a copper or gold prong that you screw onto the back. If you're unable to do this, the box for your broadcast/satellite/cable should have a three-way output, color-coded white, red, and yellow. The red and white are for stereo sound, and the yellow is for the video signal. You can route that output into the three-way input on the back or front of the VCR. This can be technically more challenging, depending on how it needs to have the input setup, for instance needing to be on a specific channel, but routing the cable through the input and output for the VCR is the simple way, and should give you no trouble.

1st, see if you can get another cable box that offers component as well as RCA outputs on the back. Does your cable box have S Video out and does your toshiba have S Video in? If so, hook up the S Video from cable box to Toshiba. Then hook up R&W audio from Cable Box out to Toshiba In. Set the channel on the cable box to what you want to record. Set Toshiba to record channel 3 or 4, whichever your Toshiba is set on. The cable box controls the channel you are recording. You cannot set the recorder to the channel you want to record. It must be either 3 or 4. Try it. If everything else fails, you have to go cable from wall to cable in on cable box, cable out on cable box to cable in on Toshiba then either cable or RCA out on Toshiba to TV.

yes your hook is all correct...but still will not work......unless this is a d-vhs recorder...(and the other way to record hd is dvr)....(note dont throw the standard vcr away) it might and can be use later down road

1st-how do you have your "cox" cable box [you could have said it was a cox cable box!!] connected.Can you 'get a picture' through the TV without the VCR ? Do that! disconnect the VCR from the line and plug the TV directly to the "cox" box.Does it work? Are any of the cables connected from cox to VCR to TV damaged.? Let me know how you have the three(3) equipments connected.

Hi Seve.
Not sure what is meant by 'HD cable box'.
If you mean a DSD (Digital Satellite Decoder), then the built-in firmware prevents recording (of composite video signal).
In our country the SP requires that you buy a dedicated 'Explora' decoder which allows recording.
HD cable technology may have introduced similar anti-piracy measures.
{reminder to me: Google "HD cable TV" :)

Make sure you are giving the VCR a signal.
If using a RF source (cable or antenna), make sure the VCR's tuner is set up for the right type and channels.
When trying to record put the TV's input to the VCR to make sure it is getting what you want.
