I’ve been maintaining a PVR350 on an old Dell 2.4GHz since forever.
Latest updates (to MythTV 24.1, and licrd 0.9.0.7) have made big changes. But it’s all working again, including a serial IR blaster. The following is just for my easy reference, and anyone else who now finds their Grey Hauppauge remote [...]

Upgrade to 2.6.22 seems to break *everything* in the ivtv suite. It all disappeared from the rpms, so we need to install from source.
ivtv
ivtv-fb
ivtv-xdriver
ivtvfbctl (now gone)
In particular, some web posts indicate that support for the PVR-350 has been eliminated somehow. This doesn’t seem to be completely true – but maybe there’s a problem [...]

ivtv
