sbiddle: With those sorts of figures for CPU load you obviously don't have a video card doing hardware acceleration. This is something that is a virtual must for the H.264 streams.

I found channel changes on MP to be very quick.


Hi Steve,

So you are saying that even though I don't see more than 65% peaks of cpu load that a card with hardware acceleration will improve video performance, i.e get rid of the tv3 jerkiness?

How fast are the channel changes? We have the same tuner card HVR3000 and our cpus are about the same performance. What is making mine slow?

mcraenz:I find MediaPortal it self to be very robust, TVServer however is still in beta, constant work is being done on it so it's stability reads a bit like a stock exchange graph! However in saying that I've been using it prime time for more than a year and find it to be stable enough, espically in last couple of months. It also depends on whether you can resist upgrading to the latest patch every other day even though you've got a stable system, if you can't resist then expect to see some issues as development continues. IMHO features the outweigh the occasional frustration. And WAF is very high which says a lot for any PVR!


Ironically I've found the opposite but then I'm definitely guilty of having the MP frontend a bit non standard. (Non standard skins, quite a few plugins) TV Server has actually been pretty good for me; although I stayed on a good version at the beginning of December until recently upgrading to a new version. Some of the Dec versions sounded like they were a bit scary but as you say that's what you get if you want to play with nightly builds.

Hopefully the old idea of MediaPortal being hard to configure or it being crap if you don't do it well is slowly disappearing. I haven't touched GB-PVR so far but my memories of poking and prodding MCE are still far too painful. Doing more on MP without any hassles is so much nicer.

I guess my only warning to people is that if I "play" with MP to try to do something "cool" then it is less stable. If I just leave it alone it's fine. So if you're having problems start with a vanilla build and configure one thing at a time and then leave it for a while before doing something else. The cool stuff is generally the newer code which isn't necessarily the most robust. Core functionality is pretty good now.

Yep, got that there too with DVBViewer



TVNZ7 has a feed (I assume live) looking across at Auckland CBD from the North Shore and a high pitched squeal as the audio.

Freeview will launch its digital terrestrial satellite service, Freeview HD, on April 2.

Viewers will be able to see 12 hours of TV3 programming a week, including shows such as Prison Break, CSI and Boston Legal in high-definition and other Freeview digital channels in standard definition.

TVNZ does not expect to broadcast many programmes on Freeview HD in high-definition, bar the Beijing Olympics, till late next year.

Another one for MSM... "Digital Terrestrial Sattelite" (Dominion Post) should be in the hall of fame with "Wireless CDMA" (NZ Herald).

Till LATE? next year?


One can only hope that is a mistake similar to the title.

But thumbs up for TV3 12 hours a week is basically all their prime time US shows.

Why do you keep knocking the launch of the service and the price of the boxes?

The question is, will tv3 move to 720p, or stick with 1080i.

According to the FAQ freitasm posted from Freeview NZ

TVOne and TV2 will broadcast in the 1280 * 720 progressive (720p) format, while TV3 will broadcast in the 1920 * 1080 interlace (1080i) format. Both provide stunning HD picture quality.

Fossie: Ugh. How stupid. 1080i is real dog.


Is 1080i really THAT bad?  Even when compared to 720p?  I would have though the extra information (being 1920x1080) would have made for an excellant picture, and any decent set should be able to deal with the interlacing and make it smooth.  1080i also seems logical as that is the format I understand lots of US TV shows are shot in (excluding sport?).

However if a viewer only has a 720p display, how will 1080i look then?  Actually, anyone know what it looks like on a 1080 panel? (I assuming we can ignore the details about viewing distance, and hope that someone who buys a 1080p display gets one big enough that they can see the difference).

Regardless of the format TV shows are filmed in IMHO is the better standard simply because it's a proper (and very expensive) deinterlacer doing the hard work before transmission rather than a cheap $5 chip in your TV that has to do the same thing to convert it into a progressive scan format so it can be displayed on your TV.

Most shows are filmed in 1080i so I suspect TV3 like many broadcasters are choosing to simply retransmit that rather than investing in an expensive deinterlacer. The fact that virtually all TV's sold these days are flat panels which are a progressive scan screen and not an interlaced picture like a CRT - interlaced video formats should be made obsolete by now!
