Hi,

coming here to ask if someone is having a similar situation as I have.

I have a PVR (Homecast) which has been working perfectly since I bought it. The issue I have is regarding the channel scanning. I recently moved to CBR and after doing a re-scan of channels on my TV, I was able to detect all of them on the right channel. However, when I perform a scan on the PVR, it detects channel SC, SCHD, ONE (mainly all channels from ten) on different channel numbers. Say, I expect to find SC on channel 5, however the PVR places it on channel 350!!! Similar with the other 2 Digital channels (One = 50, Eleven = 55; however, one = 351, eleven= 352). Reception is fine, but I can't understand why the PVR is doing this. Should I do something different?

Thanks,

[mtv]

There are two possibilities.

1. You didn't delete all channels before performing the scan at your new location... this would have retained your old location channels, plus adding your new location channels, with the higher numbering.

2. You are receiving signals from more than one transmission site.

I'd suggest performing a factory default reset of the PVR, then re-scanning.

I did remove the old mapping... I'll try again tonight. Would the factory reset delete my recorded shows? I wouldn't expect so, but who knows with these devices. Thanks

Where in canberra are you located.

If you can see Black Mountain (Telstra Tower), AND thats where your aerial is pointed, you can stop the scan after a lil over 30 (30 is SBS and the highest freq channel from Black Mountain), and your PVR should let you save anyway. That should stop it picking up stations from any of the other tranmitters that serve Canberra's suburbs.

I can tell you with my homecast (HT8000), that a firmware update doesnt affect HDD data, so I doubt a factory reset would, infact given my experience with this kind of equipment I would be VERY surprised if you lost your recorded programs.


Its not quite clear from your original message but this info will likely only work if your getting SC10 on both 5 and 350 (and similar for the multichannels). If your getting nothing on 5 and something on 350. Thats probably something completely different.

calichin,
If this box conformed to Australian Standard 4933.1 -2010 then the receiver would automatically pick the best of these signals and label them correctly. This receiver obviously does not do this.
In http://www.dtvforum....opic=11430&st=0 you will find a link to transmitter lists
As you can see there are transmitters on Black Mountain, Thorn Cres Banks, Tuggeranong HIll and Mt Taylor.
All tuners on the installation channel scan start at transmission channel 6 and then tunes every channel to channel 69.
So you probably would have got LCN 5 which has Southern Cross. The LCN channels of 350 - 399 are labelled by the receiver. If these signals are more reliable, then repeat the channel scan with the antenna disconnected for the transmission channels you do not want. For example if you wish to receive Tuggeranong, leave the antenna disconnected for 75 % of the scan and then plug it in.
The receiver will then allocate the LCNs as the stations transmit them.

Hi all,
I did the factory reset and it seems it fixed the issue. Running it now and straight away ti picked up 5 as SC.
Scan finished as I was typing. All perfect (ABC 2, 21->24; SBS 3, 30->34, SC 5,50,55; Prime 6, 60->64, Win 8,80,88)

nbound,
I'm in Crace, and my tv signal is coming through the fiber (don't ask me why or how, that's also new for me). My box is also the HT8000 and it has worked fine for the last 4 yrs! I wasn't getting SC on both channels,

AlanH,
Given the factory reset fixed the issue, does this box conforms to the standard?

nbound, a quick question for you, when you press the info button on the PVR, what does the green (top) and yellow (bottom) antenna bars mean? I have ~50% of the green and 90%~ on the yellow. Given that I'm receiving the tv signal through cable, shouldn't I get close to 100% on reception?

Thanks for your help, it solved the problem

I beleive the top is strength, and the bottom is quality. I cant confirm if that is the order because mine doesnt tell me either, and neither does the manual. I have similar readings to you and dont have reception issues.

Its my understanding that only TransACTs pay tv (and various other services) come thru the fibre. You should still have an aerial somewhere (possibly even in the roofspace if none are visible externally), or if u live in a multiple dwelling building/complex (townhouses/duplex/villas) it may be fed from a single aerial on another building to several other buildings. And even though the FTA channels do come through on TransACT, you should still need one of their STBs to decode them (Like Austar/Foxtel/etc.). If anyone actually from Canberra (im from elsewhere in the sthn tablelands) itself is here though they may be able to confirm this and/or provide more accurate info.

The program guide for TransACT shows all free to air and pay programs which are obviously all being delivered by fibre optic.  (TransACT is now owned by iiNet (a WA company)).

Considering that Prime and Southern Cross national playout centres are in Canberra it is highly likely that they can take the signal direct from them. Either way they would have to get good signals to feed their system otherwise many will complain particularly when they are paying for it. They can not have additional copies of identical programs on their fibre optic.

So it would appear that you had previous scan stored in your receiver and an additional scan meant the newly scanned signals on different RF channels are seen duplicates.

The reset erased the original stored values and now the single set of channels they are correctly numbered.

So it is unlikely your box does not comply with the Australian Standard.

In Crace and surrounding areas the fibre to the home carries the FTA services and the Transact paytv services along with data and phone.
If you do not subscribe to transact you will need an antenna tuned to Black Mountain or take pot luck with an indoor antenna.
In Forde the services were quite poor via the fibre in the early days, hopefully all that was rectified by transact as time went by.
