Sound, no picture, via DVD recorder

    We bought a Toshiba DVD recorder (RD-88DTKB) 6 months ago that is capable of recording both analogue and digital recordings. Just this week, we bought a new Toshiba TV (42AV635DB) and connected them both via the HDMI cable supplied with the DVD recorder.
    We can now tune in to the 4 Irish DTT stations on the TV but cannot ‘see’ them via the DVD, ergo we can’t record them. We CAN hear the programme audio! I have no clue what, if anything, I am doing wrong. Any ideas?

    Just to add, no problems recording analogue stations or the free sat ones either.

    Your TV is MPEG4 but your DVD Recorder is MPEG2 so while you can see the channels on the TV the digital tuner in the DVD recorder cant decode the picture.

    Thanks for the reply - is there nothing I can do? It was an expensive piece of equipment. I'd read about the Mpeg4 thing for Ireland as regards TVs but didn't think about it for the recorder :o

    Check your tv manual, if it is outputting its current signal on one of its scart sockets you could switch your dvd recorder to analogue record and record the output from the tv.

    I can already record the analogue broadcasts - all fine EXCEPT for RTE1, where whenever the DVD recorder is on there is horrible interference - wavy lines and snow. When I switch it off it goes back to being perfect. I suspect there is some kind of conflict with the way it's connected that exclusively affects RTE1, but I have no clue what. I changed the connection from the TV to the DVD from scart to HDMI and no difference, so I'm stumped :( That's why I'd hoped I could record the digital version which isn't affected by the interference.

    Sorry, I mean switch to one of the digital stations on your tv. I don't know how your tv works, but most freeview tvs in the UK also output the currently viewed digital station in analogue form through one of the scart sockets. If your tv supports this (check your manual) then you could record the signal your tv is outputting through its scart on your dvd recorder.

    Thanks again for your reply - would this mean that I could have both a scart and a HDMI cable connected from the DVD recorder to the TV at the one time? My TV seems to have this option, but I'll need to experiment a bit. I'm assuming that the downside of this option is that we can't watch anything else while the DVD is recording what's on TV?
    The OH is getting mighty fed up with moving the TV stand out and in as I check the various connections and options :) I'll give him a few days before trying again ... :)

    Yes, there shouldn't be any problem having a scart and hdmi cable connected at the same time. You would not be able to watch anything else if recording from the tv.

    So what your saying is that when you are watching the DVD Recorder through the AV Channel RTE1 on analogue is bad, the other are perfect. Right ? Are you using an indoor aerial ? Analogue unlike DTT may require that you reposition the aerial for certain channels or frequencies.

    I presume yopur aerial connection goes into the DVD recorder first and then you have a looped coax cable from it to the TV. Right ?

    What is analogue RTE1 like watching it through your TV directly? (ie not the AV channel but channel 1 on analogue).

    Sounds like wiring issue or weak tuner in the DVD recorder.

    This may all be irrelevant anyhow. The suggestions of enabling it to record what you are watching only defeats the purpose of the unit in the first place!

    Your ability to receive MPEG4 broadcasts will never happen with that unit as it is MPEG2 hardware. These combo analogue/digital DVD Recorders as such shouldnt be sold in this country - they are only suitable for the UK. There is no point in selling people digital tuner that will never work in this country. I would try and return the unit as not being suitable for use. Retailers organisations were written to the Dept of Communications over a year ago setting out the spec.

    You say it is an expensive bit of kit. I would suggest trying to return it if it was bought in Ireland only 6 months ago. Leaving the useless digital tuner aside, the analogue tuner will become obselete in the next few years too (it already happening in the UK). Thats just not good enough. How much more of this unsuitable gear will be dumped here by unscrupulous retailers !

    Name and shame. Where was this bought ?

    It sounds to me like The DVD recorder has an analogue RF output which is either on the same frequency or immediately adjacent to the RTE1 analogue freq. you are recieving.You should be able to either change the DVD recorder's rf output or turn it off altogether via the set up menu on the DVD recorder

    Well, the naming and shaming is mine alone :o as I bought this in NI at my local Argos (live near the border). I couldn't find any other hard drive based DVD recorder locally after my old one died and this seemed like my only option. Since it's my own fault and I wasn't mis-sold it, I will live with it. Mind you, I find it works perfectly with everything else - I can even record from satellite (with a bit of juggling) and it records the other analog stations perfectly. So maybe not a total disaster ...
    The aerial is in the attic and as we live on top of a hill reception is generally excellent. When the DVD recorder is switched off, the reception on RTE is perfect through the TV, when the DVD is on, it's crap - this is not through the AV at all, just the TV. And yes, the aerial goes into the DVD and then the loop to the TV. All I can think of is some kind of interference?

    This sounds like a possibility to me - I have no idea how to change the DVD's rf output. Turning it off altogether (the machine itself) does work - as in it eliminates the interference - but I'd like to be able to record RTE1, occasionally anyway :) If I do manage to turn off or change the rf output will it still record? Sorry if that sounds daft - I'm on a steep learning curve here

    If you change the RF output frequency or turn off the RF output on the DVD recorder,You will be able to record as normal it will not affect the record facility.But make sure you view the Dvd recorder via scart/HDMI connection and not through an analogue channel on your TV's reciever. Let us know how you get on. G.

    But there isnt an RF Modulator on those according to the spec sheet.

    Has to be the looped coax going from the recorder to the TV. Try another one.

    Unfortunately, STB is right - there's a notification in the manual that there is no RF modulator :(

    There was an RF cable supplied that connects the Aerial jack on the TV to the recorder - is this what you mean? I've tried a new one and there's no difference :(

    Which RTE version is disturbed?
    The digital one via your TV, the analog via your TV or the analog one at your DVD recorder transported via hdmi/scvart to your TV?

    The analogue via both TV and DVD recorder is disturbed. The digital one on TV is fine, but I can't record it because the DVD is not Mpeg 4 :(
