Can you use the HVR3000 or HVR4000 with both DVB-T and the Sat tuner with the Beta?

Would be very keen to know that, given that I have an HVR4000. Soon as my 1.5TB disk turns up I'll be able to answer though :)

As long as you don't try and access them at the same time, yes... However there are likely to be issues.

MC still see's them as independent tuners, as opposed to hybrid/shared, and will let you tune both at once which will cause an instant crash

ie On a single HVR 3/4000 under Freeview you might have both DVB-S and DVB-T channels in the guide and be say recording TV3, and then try to change channel to TV2 which will go crash/bang/bop...

So the best way to take advantage of DVB-T and an EPG is to keep my Nova-T 500 and get a single Sat tuner as a second card?

Sorry I probably confused the issue. I didn't mean it to sound like the cards themselves have issues, more so peoples expectations of them.

Both the HVR3000 and HVR4000 are very good cards. They both offer the advantages of being able to change between DVB-T and DVB-S.

If you use one and use it for a single purpose ie either as a dedicated DVB-T or as a dedicated DVB-S it will work exactly as expected, without issue.

However alot of people expect the cards to work as dual tuner cards ie tune to both DVB-S and DVB-T at the same time. Neither the HVR3000 or HVR4000 can do this.

In the case of the HVR4000 it is currently one of most easily/readily available DVB-S2 cards in NZ (Sky HD anyone?).

For example I'm currently using a HVR3000 as a dedicated "guide only" card, as per your suggestion above. It sits in the same box as a HVR2200 and a HVR4000.

Hey, been following this thread a while,

so to clarify up til now ( )

If you get windows 7 build 7000 and a DVB-T Nova 500 card, you essentially can get working pretty well for just terrestrial freeview (minus the guide) - so recording, dual tuner etc all working ok?

If you add a dvb-s card, you can set up to get the guide data..

or its a matter of waiting until some epg thing like blade runner (of old) comes along and injects the guide in to mc?

once the guide solution comes along, would you recommend as a reasonable solution? (understanding its beta so have to expect the odd hickup).

apart from loading a clean windows 7, drivers, updates ec + hauppauge drivers, are there any other tricks, patches people recommend? any tricks to channel tuning etc?

Hi, Just dl'd and installed it. Although the text at the bottom right of the wallpaper says build 6956 - I thought it was build 7000?
I've got all the HD channels working a the guild via Satelite all linked and working great together.

My main probelm is that I don't think it is using Graphics HW acceleration or something. I have a 8800GTS and AMD 4800+ x2 processor, 2gig Ram.
It works and plays the HD channels (with some stutter), but the CPUs sits at about 80% and often more.

GBPVR had nothing like this stress on the CPU's

Have I missed something, I have applied patches and updates etc.
Device manager shows the Graphics Driver as 8800GTS (prerelease WDDM1.1) - or something similar i am at work atm...

Appreciate any advice,

Cheers,
Nudge

You have the wrong version.... The one from microsoft definitely displays build 7000

OK Thanks, I've got build 7000 isntalled (now)

I still have the processors sitting at 90% which kinda sux.
Someone mentioned I should install powerdvd and tick use hardware aceeleration. I am not convinced that this would make any diff but I've done it anyway and it hasn't changed anything.

Has anyone else experience this?

Cheers,

It just worked ou-of-the-box for me on windows 7 build 7000. Perhaps you could try download the latest vista driver (beta or release) for your video card and try again (perhaps taking powerdvd off first)

Windows 7 doesn't use the PowerDVD codec anymore. It has its own h.264 codec out of the box. PowerDVD will make no difference at all.

From memory the 8800 didn't have full NVidia PureVideo HD support - this may be related to your problem. The NVidia drivers can be installed through Windows Update (these should show up as WDM 1.1 or something to that effect under Device Manager).

I've tried both a 8500GT and a 9400GT - both of these sit well under 30% CPU (AMD X2 4600) utilisation on Freeview HD, so I would say the issue is related to the beta NVidia drivers and the 8800 - its quite possible that under the beta drivers they have only included HW decoding support for the newer PureVideo HD aware cards, with others to be added at a later date (During the fiji beta the only recommend card with the beta drivers was an 8500GT).

I have tried using the Windows beta 7000 (tested with 1x Pinacle 340e USB stick with their media center driver, graphics is onboard 780G chipset. All looks pretty good, can tune the DVB-T channels but when I play them I get about 1-2 cecs of video/green screen then goes to no reception then back again/we are using a roof arial. Reception should be fine as we get a good analogue signal.
Any ideas on what the issue would be? Tuner/tuner driver or graphics driver?

RustyGonad:

Seem to recall it depends on the model ie. The 8800GT does but the 8800GTS does not...

What video card are you using exactly?

Edit: ah see you have the 8800GTS. So as stated this does not fully support hardware decoding and from what I have seen from other people with them even though it is only one thing it seems to miss out on it is the critical part it seems from a hardware decoding perspective.

OK Dug out an old 8400gt and now the processors down to 11%. Cheers for your advise. I am just a bit gutted the 8800gts doesn't have the PureVideo Support.

I need dual DVI out, So I will get a 9600gt - which also has PureVideo Support right?

9600GT will be fine.. Just be aware that it is a bigger card then the 8400GT and I suspect it will put out more heat but not sure on that.
