Issues and Problems
Ghosting noted with some lower resolution and bitrate combinations on PVR-250 model 32062, rev C185 (cx23416). The ghosting disappeared with resolution 480x480 and 4000kbps rates.
If you see an "Unreasonably low latency" message from ivtv in your logs you should probably read the page on PCI Latency.
Usually found upon install.
Best info most likely found on the IVTV driver forum on Sourceforge. See also the wiki at: http://ivtvdriver.org/
