IRQ conflicts happen when other devices, e.g., network card or sound card, in
your computer share the same IRQ with your TV tuner card.
Use Device Manager to detect IRQ conflicts. In Device Manager, choose
"View->Resource by type" and click on the "+" besides Interrupt request (IRQ).
You should see the following.
For best performance, no device should share an IRQ with the VideoMate TV
card.
If another device shares an IRQ with the TV tuner card, remove other PCI
cards from your PC and insert TV card on the third or fourth slot from AGP only
(if available). Then uninstall and reinstall the TV card driver. This usually
solves the problem. If the problem persists, you should move the PCI TV Tuner
card to another PCI slot.
After you are able to successfully use ComproPVR, install the other PCI
devices one at a time. Restart your system and test ComproPVR after
installing each card.
Note
Pay attention to the IRQ numbers of networking, sound, and SCSI cards.
They should not share IRQs with the TV tuner card.
