I'm still getting glitches in my picture of freeview HD. Using very latest powerdvd8 codecs with 8500GT, which are workinning i'm pretty sure, so thats not the issue. Updated to Mediaportal RC4 which is running slick as, channel changes are within a few seconds.

To be honest the mediacentre has been rejected for TV watching for a long time (blame mysky, HTPC mainly movies + file server), ive just had it recording a series for future archiving and not watching.
But yesterday i was watching a program from the timeshift and i noticed i get glitches every now and then. Sometimes its very frequent, up to 3 times in 10s. Sometimes it'll go fine for 5mins before a glitch.
Also the magnitude of them changes, sometimes the audio continues and the picture freezes for a second, sometimes you loose audio and the picture goes blocky and unrecognisable for several seconds.

Reception problem?
The iDTV upstairs has zero issues with reception. Setup is a 91 element UHF which i know isn't aligned correctly (its facing upwards slightly and to the left too much, need an extended ladder to reach it), then to a masthead amp combining with VHF, through the power injector to a splitter, which then runs to each room. Minimum of RG6 dual shield, quad shield between the wall and HVR-2200. In between the tuner and 8500GT theres a plastic bag with tinfoil 2-3 thick, to block out RF interference.

Thoughts? Is it the badly aligned antenna, even though the other TV has zero issues?

Got up on a 5m aframe ladder (freaky) and rotated the antenna through 1 notch and signal improved with ScanchannelsBDA-UK to around 50% with TVNZ
For some reason mediaworks (698000) gets full reception no matter how i angle it.
Kordia is still low though, and it says no signal sometimes.

Masthead amplifier is easily 10 years old, was put in when we got Sky UHF, which i can't remember when we last had it, so long ago.

Oh well, perhaps we can swap the amp out one day for a newer one.

Some of the older sky stuff was band 4 only, and also if the cable is breaking down you tend to lose the higher freqs first.

Cabling in the walls is new enough i think. Cable to the UHF has been replaced as we put the 91 element in a few months ago. So pretty much only the VHF cabling is old stuff, and the old kingray masthead amp, which we discovered not long ago has been running without a power injector for many years.

Any idea why i get 100% reception on the mediaworks mux but so bad with the TVNZ one?

The different strengths is fairly common simply because the channels are on different frequencies and your aerial will respond differently to them.  In some cases the new channels are all broadcast close to the existing prime UHF frequency so the existing aerial will be fine.  In some cases though there is quite a difference in the frequencies. 

You also have to consider where you are and if you are receiving all your channels from the same transmitter, if you are in an area with more than one transmitter site.

I have an antenna that was put up 5 years ago to get UHF and VHF reception but it was never that great and when I got cable, it was never used. I now use it to get FreeviewHD from Kaukau. I don't watch live so don't notice glitches but I do see them in the recordings I make. And it plays havoc with processing of the files since the DD track drops out at a glitch. No problem with watching since the timestamps fix that but real problems with converting files to smaller formats.

Converting is an issue also for me, i don't watch live on the HTPC either.

Our prime coverage is shot to hell, so is TV central and maori, all analogue UHF channels broadcast off Te Aroha.
Hence why i find it odd mediaworks is 100% and every other channel is rubbish.
