This card has the potential to be fantastic - 2 tuners in a single PCI slot.

Unfortunately, due to some kernel driver problems, it experiences intermittent USB disconnections. This requires a restart of the MythTV backend, or sometimes a reboot of the whole system. The remote control is currently unsupported.

Setup is a pain on anything other than MythDora (and even then it's easy to get it wrong), requiring quite a bit of hacking to make it work. Some useful instructions can be googled easily though.

The USB disconnect issue is supposed to be fixed with kernel 2.6.21. Not seen anything with regard to the remote control support.

This 32-bit PCI card presents itself as a USB device. The guts are the same as the USB models, plus a USB/PCI bridge.

CPU overhead while recording MPEG2-TS to disk is minimal, about 1%. MythTV can be configured to record multiple channels from each tuner if they are on the same MUX (frequency).

Driver issues such as USB disconnects and IR support have now been fixed and the card works "as advertised". If you have trouble with older 2.6 kernels then check the v4l-dvb web site for drive updates. Errors are usually with the dib0070 kernel module. Suspend/resume also appears to work.

IR reception is marginal with some keys being misinterpreted by the kernel drivers and/or LIRC. I would not want to depend on the Hauppauge remote exclusively. There is no way to turn the PC on from the remote - the card lacks the required hardware.

The card does run hot, even in a well cooled case, but appears reliable. Mine has run for one year now, 24/7.

If you want a dual tuner DVB-T card for Linux this is just about your only option.
