Why won’t my digital TV tune to the service correctly.
- To correctly tune to all the digital services your TV or set top box needs to be MPEG 4 (Saorview) compatible. Some of our services are transmitted in MPEG 2 and some are MPEG 4. For example the saorview services of RTE, TV3, and 3e are all MPEG 4 where as BBC, Eurosports, Discovery etc is MPEG 2. We recommend using MGEG 4 Saorview devices to receive all the available services and saorview digital teletext. The newer MPEG 4 standard is backward compatible and can also understand MPEG 2, but the older MPEG 2 cannot tune to the more advanced MPEG 4 services.
- To correctly tune your equipment, in the tuning menu you should select Antenna as the tuning option as opposed to Cable. Some TV offer different country options and Ireland should be selected as the preferred country option. If Ireland is not available, Netherlands is the next best option to choose followed by England as the third best option. To recieve saorview digital teletext you need a soarview compatiable device and the country option Ireland needs to be selected.
- Not all flat screen TV have a digital tuner and others older flat screens may only have a MPEG 2 digital tuner. General rule is, TV’s purchased before Jan 2011 may not have an MPEG 4 tuner. On your remote select DTV to get digital TV options. Please check your TV manual to see the full specifications of your TV.
- RTE now only transmit digital teletext. In order to receive this service your device needs to be able to understand “MHEG 5 interactive services”. True Saorview approved TV’s and set top boxes support MHEG 5. Please note there are some early release devices that are Saorview compatible but do not support MHEG5. Please consult your manual / TV dealer to see does your device support MHEG5. If digital teletext is important to you, make sure you purchase a fully Saorview compliant TV or set top box.
- Is your device a UK Freeview TV or Set Top Box? Most Freeview equipment is MPEG 2 only. Some newer Freeview view labelled equipment may be able to tune to MPEG 4 but most likely will not have MHEG 5 for receiving RTE digital teletext. Please note that the first generation of UK Freeview Digital ready TV only had MPEG 2 digital tuners.
- If the picture is smaller than the screen you may have to change the picture aspect ratio settings in your TV menu.
- CableComm transmit the channels so as to assign the channels in a logical order, RTE1 on No1, RTE 2 on number 2 etc. Some TV do not understand logical channel numbering and tune services in other orders. If this happens you need to order the services in the TV tuning menu to your liking. Selecting Ireland as the country option in the tuning menu may better help with ordering the channels correctly. If you digital TV channels are starting at 800, this may be due to your country setting not being selected as Ireland.
What are the analogue tuning frequencies of each TV channel?
The following are tuning details for tuning your TV to the CableComm analogue basic channels. The following is a guide as different brands of TV’s use different details for tuning.
Example: For RTE 1 newer TV’s use Ch 05 (and may need to be fine tuned) where as older TV’s use VHF High as the tuning band.
The details below are correct as of July 2017. The list is a guide only as some brands of TV may differ from the tuning details given above. If the details do not correspond with your TV, please refer to the dealer who supplied your TV.

Why do I have digital breakup or analogue snowy pictures?
- If your cable signal is passing through your VCR, check that your VCR is powered on. If your VCR is no longer required plug your antenna directly into you TV.
- If you have a wall outlet installed by Cablecomm, confirm that you have picked the TV Data port on the white wall socket (right hand port), and not the FM radio port (left hand port).
- Confirm that all connections are tight.
- Only use high quality metal cable splitters. All white plastic splitters should be removed as they are not of high enough standard to handle the amount of digital TV channels we transmit.
- Have you had new windows or fascia boards fitted, if so, has the cable been damaged during their installation ?
- If your pictures are breaking up on RTE, TV3 or TG4, confirm that you haven’t accidentally tuned your TV to UHF off-air reception. Please use the tuning details above.
