Hauppauge Nova/HVR CX88x

From DVBViewer
Jump to: navigation, search

The Conexant CX23880/1/2 chipset can only handle a single concurrent digital signal (hardware limitation), therefore it is not possible to tune DVB-S and DVB-T simultaneously (e.g. HVR-3000, HVR-4000). This limitation does not affect the PCI-Express Conexant CX23885 that is used on the new HVR-3300 and HVR-4400.

This page is broken down into each tuner type (DVB-T, DVB-S and DVB-S2). For combo cards such as the HVR-3000 and HVR-4000, you should look at both the DVB-T and DVB-S/S2 sections of this page.

[edit] DVB-T Tuners

Nova-T-PCI, HVR-1100, HVR-1300, HVR-3000 and HVR-4000. The chipset is the Conexant CX23882 combined with a Conexant CX22702 demodulator. Tuner is either a Thomson DVB-T tuner or a Philips Hybrid tuner.

[edit] Driver Issues

  • HVR-1300: IR remote causes system freeze with HyperThreading or Dual-Core CPU. Install the latest driver to fix this.
  • HVR-1100/1300: BDA Signal Strength is calibrated on-the-fly. BDA Signal Quality appears to be accurate. You can install the [Hauppauge Digital Signal Monitor] which gives proper readings. The Hauppauge signal monitor can be installed without installing the WinTV software and should be run with DVBViewer running.

[edit] Hardware Issues

  • NOVA-T PCI (90002): RF-passthrough is very noisy (not present on current 90003 model)
  • HVR-1100/1300: Earlier revisions (2004/2005) appear to have issues locking weak digital muxes adjacent to a strong analogue signal


[edit] DVB-S Tuners

HVR-3000, NOVA-SE2 and NOVA-S-Plus.

[edit] Driver Issues

  • HVR-4000: DVB-S tuner won't work after sleep on Windows Vista and Windows 7 unless unless the DVB-T tuner is used first
