Sorry cantbebawt but emailing the solution to you won't help anybody else with this problem.
With all problems you need to go down to the very basics. This is also very helpfull when your system has a specific problem like locking up or crashing.
Step 1) Back up all your data or use a spare drive that you can format.
Step 2) Disconnect any hardware from your system that is not required. E.g. Sound card, modem, network card.
All you need it a motherboard CPU, your Ti4200 hard rive floppy drive and CDROM inside your case.
Step 3) Install a new install of Windows XP and the latest Service Pack
Step 4) Install the latest Motherboard Chipset drivers, then install the latest DirectX and after that the latest or Video Drivers (from
Step 5) Install the WDM 1.22 and then your Video Capture software make sure that you set the region settings for your country (PAL if your in the Pasific region NTSC if your in America etc...). You won't need to uninstall the "Legacy Video Capture driver"
Step 6) Confirm you have no resource conflict in the Device manager. If you do reboot and try to reconfigure the IRQ's manually in the BIOS setup.
Step 7) Connect your VideoIn on your Video Card to the VideoOut on your TV/VCR. Run your Capture software, set your capture settings Video Composite if you use the RCA Jacks or S-Video if you use the 4pin mini DIN port (Default is set to TV Tuner). Make sure your display/View mode is set to Overlay and not Preview. You should get a signal now.
If the picture is cut short try to reconfigure the overlay size in the display properties or in the Capture software.
Also make sure again that your Region encoding is set to the right mode (PAL or NTSC and so on...)
Step 8) If you have done the above 7 Steps right and you have a video feed, you can power down your system and start installing one by one each of you other adapters checking after each install that your Video Capture still works. If you find that one of the adapter cards causes problems try moving it to another PCI slot or swapping it with another adapter in your system.
Hope it works for you as it worked for me!
Cheers
