Ok, so - a week ago today - I brought a Hauppauge HVR900H from eZone Takapuna.

I got home, installed it (all fine) and found that it gets no reception with the little stick aerial it comes with.

So, on Monday I went and picked up a new UHF Aerial for my roof, I set it all up etc. and it works great.
Picks up all the Freeview Channels perfectly no problems.

But. There seems to be a problem with either the Power Cinema 5 I'm using (which came with the HVR900H on a disc)
or maybe it's the HVR900h itself...

90% of the time, I plug 'em into my PC (which is far capable of handling the signals and whatnot as when it does work
I have no problems at all) and I open up Power Cimena and click the TV Icon and then that little yellow crescent appears,
and doesn't stop spinning for as long as I've had patience to wait (30+ mins). I've tried updating PowerCinema to the latest
version, but that doesn't support H.264 decoding in the TV mode (so it says), once I reinstall PowerCinema it works fine, opens
up, scans for channels in the startup wizard and I can watch and record TV perfect for a day. Then the next day it will pack in and I have to repeat the process.

On top of all of this, occasionally when it does work, it will record to a 4kb file, which really pissed me off on Monday night when I hit record on Beat Squad, then came back to the PC at 8pm to watch what it had supposed to have recorded, but I was left with this useless 4kb .mpg (Transport Stream) file.

And, just before you say - DVBViewer never finds any channels either, I follow Fossies guide to every single word and right up until the "Scan Range" part, it never finds anything (which is wierd because when Power Cinema does work I have 5/5 Signal strength, plus I can see the transmitter from my roof, and that is where the end of the UHF aerial is pointing).

Soooo, is anyone else having the same problems, what would you reccomend I can do?

I'm running XP SP2 with AMD Dual Core and 2 NVIDIAs in SLI btw.

Thanks!
