NVidia Capture Driver VS Leadtek TV Tuner problem

Question

I previously have used Leadtek WInfast TV Tuner 2000/XP before I installed MSI Geforce4MX 460-VTP with VIVO.
I never installed the capture driver for the Geforce card though, because I do not see the need. Besides I prefer to use the tv tuner to record my tv programs.
Another reason why I didn't install the NVidia capture driver is because I realize that it will cause some conflicts with the Leadtek TVTUner card driver because both are actually installing the same device drivers for the same tv-chip hardware located on both card.
NVidia Capture Driver will install these hardwares in Device Manager:
- Nvidia WDM Audio Capture
- Nvidia WDM Crossbar
- Nvidia WDM TVTuner
- NVidia WDM Video Capture
while, the Leadtek TVTUner driver will install the same driver for its own hardwares:
- Winfast TV2000-XP Audio Capture
- Winfast TV2000-XP Crossbar
- Winfast TV2000-XP TVTuner
- Winfast TV2000-XP Video Capture
Surely installing Nvidia Capture driver & Leadtek TV TUner driver will cause WinXP confused because it finds 2 sets of the same hardwares.
As I previously explained, I currently didn't install the Nvidia Capture Driver, and relies mainly on the Leadtek TVTuner to watch tv programs.  The problem is when I tried to use some recording softwares like TVTools, these softwares will only find the NVidia TV Tuner hardware instead of my Leadtek TV Tuner.  
How could I solve this problem ?
Is there any way to make both hardwares (Leadtek tv tuner & NVidia capture driver) work together ?

Answer 1

It's got to be either a configuration issue or an incompatability with hardware because I have installed several of those cards on friends and client PC's without a single problem. I will say they all had nVidia VGA cards and either the nvidia or via chipset. I also have one and I can't find a better card for the $ and the ease of use, nice clean straight forward GUI and stability.
Have you tried the latest drivers and PVS from leadtek's website?
This thread should be in the VGA forum with a link here just in case a user with your mobo has this card.
It's not in a shared slot is it? Have you looked for IRQ conflicts? Try removing the bluetooth and modem temporarily so you only have that one TV card, then check the IRQ's. If you have to move the card to another slot. The best slots are the second and third one down from the top (where the AGP slot is) and not the first and the last slot. Try operation then. Does this fix the problem? If so then you have to find the best slots for the BT and the modem.
Good luck.
