Hi
I can´t get the tvserver to work ok if i use both Hauppauge Nova-TD-500 tvcards, the picture stutters evry 5 to 10 sekunds
making recordings or livetv unwatchable. If i have all 3 cards enabled in tvserver config and use 1 or 2 of the tuners for
livetv or recording itis all ok, but if i record on 3 or 4 tuners i get stutters and the tvserver stops responding so i cant
switch channel in mediaportal or start a new recording, but i can watcha movies from the hdd that are alredy recorded,
mediaportal is ok. I cant record 4 channels on 4 tuners (one on eatch) whitheout stutter but i can record 10 channels at the
some thime as long as i dont use mor than 2 tuners it is fine. And it dosentmather if i use 1 tuner on each card or 2 tuners
on one card, it works as long as i dont use mor than 2 tuners. But it is only whith the Hauppauge Nova-TD-500 cards, if i use
the Terratec Cinergy 2400i DT card and max 2 tuners from the Hauppauge Nova-TD-500 cards (i disable 2 of the tuners in tvserver setup)
i can use 4 tuners, and recordings, livetv and tvserver works. No problem whith switching channels or start recordings.
I hope some one have some tip to make it work.

Sorry for my bad english i hope you understand. :sorry:

Do they work with the hauppauge software correctly, last time we had someone asking about using 2 x happauge dual dvb-t tuners, he could not get them to work, even with their software.

I havent tryed the hauppauge software at all so i dont know but i will try it later.

Isent the Callifo's DVB-Patch only for xp ? Iam using vista.

 

[Win7]

The patch is only for XP!

Can you just post all informations written on the via chip of the card? I am not sure if it was this card but i saw a picture of a dual tuner card from hauppauge and wondered about the via chip on the card. Because as long as i know via doesn´t produce anything for tv. So i started googling for that via chip and found out it was a usb-controller! That means the card that i´ve seen is an usb controller with two usb dvb-t sticks integrated on one card. If this was the same card like yours than we can do some tests. Maybe there is even a driver from another company with the same hardware ( i´m using terratec drivers for my hauppauge hvr-930c ). Well but some things can be done before. You can try using other slots for that cards, while doing that you can write down the informations I would prefer the second and third pci slot. Currently i have done some tests with via usb controllers and here is the bad news. If i use 8 dvb-t Tuners connected on an via usb controller the cause stuttering streams. If i use the same tuners with a nec usb controller in the same slot everything is fine. I have done a stress test on my windows 7 machine with the usb tuners and the tv-server, there is no problem while recording 26 channels at the same time, except i use the via controller!

The VIA usb controller is one of the issues the T500 has, as far as I know there is no workaround for this, but if anyone knows of one, please tell

 

[Win7]

Damn so i´m right. Ok so just can anyone send me the drivers inf file?

Well there are things you can try. The gratest Problem is running the via controller in a slot where it shares the interupt. Today i testet a via usb controller again and it did a good ( not great but good ) job but i had to but it in the second slot after the graphiccard. Slot two an three are good, slot one and four are bad. And be sure its not in a slot sharing the irq with an via firewire controller, that can mess things up! At moment i´m self in some usb troubles and i think the best usb controllers are from intel, but they aren´t selling standalone controllers. But i have seen something interessting. Intel controllers reserve only 10% of bandwith for system use all other controllers ( via, nec ) reserve 20%.

Hi

Here is a picture of the card, i have 2 in the computer, the mb only have 2 pci slots so i cant move the cards.

 

[Jare]

Sorry i forgot the driver files her it is.

Have a look at the hauppauge forums too. I'm sure I've seen people complaining about not being able to get two cards of that type working together:
