Any IRQ experts out there. Trying to get a USB Win TV device working but it crashes out. Tried everything and the only main advice the technical support could come up with, was conflicting IRQ between graphics and usb. IRQ 16 was shared, running apic so cannot change the IRQ but disable thte usb IRQ and it still crashes the app.

Any suggestions.

Dave. :(

Dave

Try moving the WinTV card into a different slot to force Windows to assign it a different IRQ until it either has an IRQ of it's own or works happily sharing with something else. This is a problem I experience loads with a audio/video PC I have full of cards :(.

IRQ management is still cr@p in XP unfortunately!!

Thanks for that dave, but this is connected through a usb port and the usb port is sharing the IRQ so I cannot shift that and there is only one agp slot so i cannot shift that either !

Any other thoughts?

Dave.

bttt for any other thoughts !

Sorry Dave,

Didn't read it properly and thought you meant a PCI card. Changing IRQ's with USB devices and XP is a real pain. XP controls IRQ allocation totally and you can't move USB devices. However, some people claim to be able to use BIOS settings on their motherboard to force XP to reallocate by reserving IRQ's. I've tried it and it's not worked for me, but could just be my motherboard. It's worth a try.

One thing that's a little odd is you mention you have IRQ 16 shared, but there are only 16 IRQ's and they are normally numbered 0-15.

I've had IRQ conflicts Hauppauge hardware myself. Does your device have an XP certified driver? With XP compatible hardware and drivers this shouldn't happend anymore. Thats the theory anyway!

Dave

You running AMD or intel?

I had one of those usb jobs from Hauppauge and had nothing but problems with it.

Basically, they only really guarantee the USB jobbies to work well with Intel chipsets :(

I cannot remember what the exact problem was with it now, but it did involving crashing and hanging if memory serves.
I just use a PCI one now without issue and the quality/performance of the usb one is cack imho:(

All of my AMD stuff runs on Via chipsets fyi.

Sorry that this doesn't help, but back then I did everything with it and had no real joy.

Cheers,

Nick :)

Win xp is crapper than a crap thing on a crap day

Dave G,

Mr Footlong,

AMD and the latest via chipset, haupaugge says this is not a problem anymore !

I have gone for a usb for two reasons, One I wanted digital tv which gets hot enough outside the pc rather than overcooking the internals. Second I got feed up with these problems on PCI boards so wanted to try something different.

I have managed to get the software working now, but not displaying video or sound !

Dave.

Dave,

I have the same set up as you. To fix mine, I downloaded the latest XP drivers from www.hauppage.com

Eagle,

I have downloaded 1.44 drivers for the nova usb from .co.uk but couldn't find anything on the .com for the nova .... which did you download that supports uk digital

ta.

Dave.

on the UK website they have 1.46 drivers not 1.44. maybe you dont have the latest?

make sure you install the drivers before you plug the device in, and that you plug it in when the machine is booted up.

Had the 1.44 on cd ... tried them wouldn't even scan ! .... Now running 1.46 not 1.44 as stated above still having problems .... :(

Know the thing is being found and talked to as it picks up all the stations just won't display the pictures

Dave.

have you downloaded the patest viewing software?

do you have a good aerial signal?

I also have the WinTV USB hooked up to an AMD powered XP driven PC ... it works, for about 30 secs - then crashes!

The only way I can get it to work is on my Intel based Win98 Laptop :(

I have tried everything from the latest s/w & drivers, latest BIOS update for my ASUS m/b ... no joy! Not that bothered though, I only bought it to transfer some video to AVI format - and I did that using the laptop.

- Jon

Cheers for the help....

After getting through to somebody a bit better I did get the new bios option .... Plus if you read the support website it details it does refer to the intel preferred and suggests buying a PCI USB card just to get it to work ...

Saying that I managed to "Frig" the software by using some of the developer stuff to get the picture and sound to work. Now I have managed to do it, the picture is jerky and blocky of some major channels.

Time to call it a day ... pack it back in the box and returned it to PC World ... That is even what the technical support suggested !!!!!!

Dave :)

Sorry mate. Been there, done that :(

Nick.
