Are there short interruptions in the sound between different sections of the programme when 1080p is used? That seemed to be the case at the start of 1080p.

Scott: They are not there in the broadcast - the audio is carried as a separate stream from the video data, but some equipment, including Sony TVs are having problems - BBC HD quietly begins broadcasting in 1080p, but not all Sony HDTVs can handle it -- Engadget has some details.

Briantist: Yes, it's a Sony. Thanks for the link. Is this likely to be fixable by software upgrade?

Scott: Yes, it should be fixed by a software update. Keep an eye on the Freeview and Freesat set-top box updates | ukfree.tv - independent free digital TV advice page.

Briantist: Sony offer firmware upgrades and updates via their website. Is the type of upgrade needed to deal with the 1080p issue capable of being delivered via internet/USB or are you are saying it can only be done as an off-air download?

Scott: No, if you want to do it online or via USB that is OK, but the fixes will also be provided "over the air" too.

james Mulholland: Film4 is on MuxD which is transmitted on C65 from Black Hill. As this is the highest frequency in use on this transmitter it is likely to be the first one to be affected by obstructions in the signal path (trees, tall buildings etc), deterioration in the aerial condition or faulty connectors/cables. It could also be a case of single frequency interference caused by the RF modulator of a VCR or Sky box blocking the required signal. At this stage it is probably not worth investigating the problem as switchover step 2 is on 22nd June 2011 when MuxD becomes MuxArqB on C47 at 100kW.

I have a tv with built in freeview hd but i cant get any hd channels. when i search it returns 0 channels found. I thought it was just because of the switchover hasn't come to blackhill yet and it was not strong enough but recently my parents got a new tv also with freeview hd built in and they get all the channels. What could be wrong here

Michael: look back though the thread. The HD multiplex is a temporary signal operating at 10 kilowatts from an aerial further down the transmitter mast. If you have driven along the M8 recently, you should have noticed a brand new transmitter alongside the existing one. On 22 June the HD signal will move to the new transmitter at a staggering 100 thousand watts* so your reception should improve then. Just be patient.
* Note: use of the word 'staggering' is poetic licence as it is not as simple as saying that the signal is 10 times stronger. I have been corrected on this point (10 dB increase).
