Hi, New to the whole Freeview game...I've just installed a Yess DVB-S2600U box,connected via RF (ONLY option) to an old Sony CRT TV. The option in 'System setting' for changing screen format 16:9 to 4:3 is not there, and the picture is laterally compressed (i.e. tall and skinny).

Is this due to the inability of the TV to accept an aspect change, or just a bad box that needs to be replaced?

4:3 and 16:9 are scanned using same timing so TV can not tell the difference.

Thanks...but would that explain why the 'Aspect Ratio' setting option is not available (i.e. completely missing) from the preferences menu? Is the box recognising that the Freeview sinal is full-time 16:9 and so making the 4:3 option unavailable?

I'm guessing it's simply not capable of modying the aspect ratio of an RF output and passing it through in the native format.

Sounds right...would just be definitively sure so that when we do upgrade the old CRT I can be sure that the STB will output in 16:9...although I guess it must be already if signal is compressed laterally, the TV must be compressing the widescreen down to fit 4:3?

Well it could be a case of the box actually setting the anamorphic flag on the RF output but the TV doesn't understand anamorphic analogue broadcasts!

As stated, the TV has know idea, only you know it is 16:9 and perceive it has being compressed horizontally.

Get an actual Freeview receiver, not some cheapie; not only will it work with widescreen, the picture will be better and you will be able to get the proper TV guide

With a DVB-S receiver you get a 8 day EPG whether you have an approved receiver or not since an EIT EPG is broadcast along with the MHEG5 one. There are also no guarantees the picture quality will be any better or whether it will resolve this issue if it's to do with the TV.

That wasn't my question thanks.

As I said my knowledge of Freeview is minimal, the question I asked was specific to the receiver I bought, and the configuration I am using it in. If I want smart-arse responses such as "Get an actual Freeview receiver" I'll post another question in this forum, until then I'll go elsewhere.

It's encouraging to see that in addition to wine snobs, coffee snobs and car snobs there are Freeview snobs too. The world needs more jerks.

AFAIK

RF does not support 16x9 signalling.

It does via SCART, this because there is a signal sent over pin 21 which tells the TV which aspect ratio to use.

The 16x9 pictures tha are broadcast over the TelstraClear cable network for example, are encoded with the horizontal bars as part of the picture.

The TV is 4:3 and wouldn't know what WSS was anyway. Up to the set top box to provide the correct format.

RF supports 16:9 if you broadcast in anamorphic. Analogue OTA anamorphic broadcasts are very uncommon however. 

I was speaking to somebody last night who told me there is are no STB's he's played with or installed in NZ that do anamorphic output on RF. The best bet is probably to find a newer TV with composite inputs.

Thanks ++ for responses.

TV is a hangover from the '80s, second set in dining room waiting for upgrade to LCD panel. No longer want to keep donating $25 a month to Sky (on top of MySky sub) so wanted a cheap Freeview box. Other than the TV's limitation on aspect ratio Yess box works well, ability to plug a USB drive in a plus although with MySky I doubt I'll ever do it.

Thanks again.

One i was playing with which had progressive out would only letterbox the other outputs if the progressive was turned off, I am assuming they (mistakenly) thought that all progressive tvs were widescreen.

Also WSS does work over RF - but I have only had any luck on it in NTSC mode on the old xbox, PAL and the tvs ignore it. No biggie since I prefer NTSC on the CRT's for less flicker.
