The BTvision manual says that if you have HD set then there is no RF output ... however this is untrue as we use it to display the viewed channel in the kitchen (the missus wants to watch her beloved Chelsea when on Sky Sports and she is often chained to the sink ) - but it is chopped to a 4:3 window (ie 16:9 with black columns either side). Does anyone know of a setting that removes these black masks? - or is it a 'feature'?

PS we have the Vbox set to 1080i and use the HDMI output to drive the TV - the sound used to be out of sync on the RF output but it has been fixed sometime in one of the updates.

PPS if set to Standard 16:9 - then the TV gets it via the HDMI cable and the RF is then correctly also 16:9 - but then the TV 'upscaling' is not a patch of that on the BTbox.

Incomplete feature

basically, the 4 res settings work as follows.

4:3 - changes aspect on both scart and RF (vid out 1 as windows sees it)
16:9 - changes aspect on both scart and RF (vid out 1 as windows sees it)
720p - changes aspect on HDMI and turns HDMI ON (vid out 2 as windows sees it)
1080i - changes aspect on HDMI and turns HDMI ON (vid out 2 as windows sees it)

the bug is, that when you enable 16:9 for the widescreen HD settings it reverts the vid1 scart back to 4:3.

instead what BT need to do is enable the settings page and keep BOTH sockets active. they need to later the aspect ratio page so that settings 4:3/16:9 alter only the scart/RF, and that 720p / 1080i alter only the HDMI.

so instead of saying select your mode, it should say select your scart /Rf mode and also select your HDMI mode if you use it.

if you unplug the HDMI cable if set at 720 or 1080 then vid2 disconnects and reverts to vid1 and sets the proper res.

it used to be set so only HDMI or scart, but BT have since enabled both to work but rather haphazardly, since many said they'd like to record from Bt to a dvd recorder, quite understandable that. Twas the famous D8 update that enabled this.

I now have the BTvision box set to 16:9 'analogue' which gives the correct A/R on the Kitchen TV (via RF) and transmits analogue (via the HDMI cable) to the main TV. We normally only require this when we want to watch ESPN or Sky Sports - and in those circumstances the analogue smoothing improves the crappy pictures if anything - so it will do for now!
