Hi Guys. I have the following..Sony Bravia KDL-40V4000 TV, Sony DAV-DZ870W Home Theatre and RDR-HX750 DVD / Hard Drive Recorder. All connected with HDMI cables and running off a UHF arial. The picture quality is perfect when watching ALL channels straight to TV. But when watching TV3 that has been recorded to HDD or watching TV3 via DVD / Hard Drive recorder the picture is bad, ghost shadows and you can't read any words that come on screen. I hope this makes sense. Any ides as to whats wrong. Thanks in advance.

You'll be using the in-built DVB-T tuner in the Bravia I imagine? (I have one of those, they're a good set). If so, are the other devices digital receivers?

Try tuning the Bravia analog receiver into TV3 and see if it's the same quality.

What quality settings are you using when you record TV programs using the HDD/DVD recorder?  If this is set low quality you'll get more recordings on the hard drive as they will take up less space.  The downside is the quality will be worse.  Sounds like you're recording with low quality setting and I'd start by looking at this.

You can only record analogue terrestrial TV on the DVD/HDD recorder so the picture quality will be nothing like the digital tuner and will also only be 4:3 and not 16:9 widescreen.

You could possibly try checking your VHF aerial and see if that's OK.

The difference is when you are watching the TV directly you are watching a DIGITAL broadcast which at a minimum for TV3 is upscaled to 1080i or may even be an HD program.  What is being recorded on the recorder is an analogue broadcast in SD 4:3 crappo-vision which will be the same quality as the analogue portion of your TV tuning, i.e. in the VHF band. 
Is the aerial connected through the recorder to the TV?

I'm assuming you are in a DTT reception area.

TV is connected via recorder. Recorder is set to HQ. I live in Northwood Chch. I'm starting to understand the problem now. All signals are great except for TV 3, need to look at a better arial maybe ?

First off I assume you are using the Digital Tuner in your TV to watch Freeview|HD?

If you don't mind only being able to record 4:3 analogue broadcasts then fixing the aerial is probably the best option. You will never be able to record anthing that delivers picture quality anything close to what you receive on Freeview|HD using the TV's digital tuner with your DVD/HDD recorder, to do that you will need a Freeview PVR box.

DVD/HDD recorders are basically obsolete technology now since they are incapable of recording any HD content, when analogue TV broadcasts shut down here in ~5-6 years time they will become worthless.

correct, which is why the reception will be bad coming in via a UHF antenna.

TV3 is actually on channel 6 (188 to 195 MHz) VHF high band or band 3 from Sugarloaf. Power is 57 dBW (500 kW). Reception is OK for analog some 400 metres north of Northwood Boolevard (small world) but I simply toss anything with an analog tuner and refuse to watch analog in the house. The only band 1 channel is TV1 on channel 3 (61 to 68 MHz).

You are correct.. it's dependent on location which (RF) channel a station is on - I was more meaning that "yes, TV3 is on VHF, not UHF".
