ok, I saw a glitch tonight at around that 40 second timeframe on tv3 news recording. it was quite noticeable with lots of blocky pixelisation for a half second.

I then dropped out and tried a few other recordings - couldn't see it at all with the kids "dora" recording from channel four. on tv1 news, something was there, but more like a millisecond of ghosting. I really had to try hard to see it. I tried another tv1 recording - natures great events - and there may have been something there, or not. Was hard to tell.

Question: how much of an issue are these glitches for you? They really wouldn't bother me at all based on what I've seen. Is it worth reinstalling etc?

Well. Looks like the microsoft foundation TV/DVD decoder is the culprit for the 40 second video glitch.

I shrunk my Win7 volume and created a second partition. I configured Win7 32bit on the new partition and can select either 32 bit or 64 bit Win7 from boot manager. 

I have so far done the following:

Bought 32bit win7 up to date with windows update including service pack 1.
Installed Avast Free V7.0.1426
Installed Google Chrome
Installed Hauppauge Drivers from WinTV7_CD_2.3d
Installed Latest ASUS drivers for: Intel P55 Chipset, Marvel Sata 6Gb, NEC USB3, Via HDAudio
Did a quick and dirty setup of media centre. (will worry about configuring tuners properly later)
Pointed the Recorded TV location to my existing recordings.

Playback of recorded FreviewHD H.264 TV still has a video glitch at around 40-50 seconds although it so far it hasn't been as noticeable as on 64bit MC. On 32 bit so far it seems to be a momentary brightening or flash on screen rather than the pixellation I have on 64bit.

I have since installed the Shark007 codec pack. Under the "Swap" tab I have disabled the microsoft TV decoder and enabled alternative decoder support.

Since doing this the 40 second glitch seems to be gone. I have however seen some random pixelation on a simpsons recording during a fast zoom so I'll have to watch some more to see if it really is improved.

The video is still not silky smooth however, During fast pans, credit rolls etc I can still  see jerkiness in the video.

I will try and get some support for the shark007 setting app and do some more tweeking.

Is anyone else using the Shark007 codecs for media centre Live TV with FreeviewHD? What settings are you using?

Regards Allen.
