Continuing from the other thread...
eXDee: We replaced our 21
element UHF with a 91 element UHF, which is connected to an amplifier
which was installed for sky uhf before sky digital even existed.
Freeview HD works fine in the iDTV, perfectly clear but the HVR-2200
downstairs is very very stuttery and has errors through every
recording. Only two devices plugged in and unplugging the iDTV makes no
difference.

Located in Hamilton, No line of site to Te Aroha as there is a small hill directly in the way.

So would i get a diplexer, or a new amp?

Brunzy: Do you have a 3 or 4 way splitter?

If so, you should terminate the unused ports or replace it with a 2 way.

What does it say on the signal information on your idtv?

Dose the hvr 2200 work if you bring it upstairs to the idtv location?

You may not even need the amp,can you bypass it temporarily?


Splitter is 2 way.

I ran a cable straight from the power injector bypassing all the internal wiring to the HTPC.
So now its running UHF Antenna > Old Amp (cant bypass, hard wired) > 5m of cable > Power Injector > 10m of cable to HTPC.
Heres the outputs from each mux below, scanned for 2-3mins each.

Your wanted channels ( 46-48 50) all show 100% quality,but then again so does almost every other channel.

Not sure I I would take them at face value.

What readings do you get on the signal information bar on your TV?,especially the BER?

And,was the signal still breaking up,when you did this?

No, picture is still stuttery. TV3 is worst i think, or the whole mediaworks mux.

And before decoding is mentioned, i did a manual recording and played them back on another computer where the exact result is seen, and TSCutter reports hundreds of errors in the file.

I think the issue is the fact its not consistant 100% quality, it drops a lot, hence the picture being stuttery.
