Description

The Newest version of HAUPPAUGE PVR-250 popular Video capture card is called the WinTV PVR-250 MCE. Despite the name, even the latest cards work under Linux with the ivtv drivers. There are cosmetic and functional changes between the revisions of the PVR 250. The PVR-250 MCE drops the connection for the remote and the 1/8" line in jack, and adds stereo RCA audio inputs and FM radio tuner. The picture on this page is of an older revision of the PVR-250 that has the remote connection, but no RCA audio input, and no FM tuner.

Encodes MPEG-1 and MPEG-2, but does not decode. The PVR-350 does both.

Hauppauge no longer ships any of the analog only (PVR) cards due to pressure from FCC.

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.

The PVR-250 and other PVR-xxx cards using the ivtv driver sometimes suffer from a DMA problem. In some cases, this results in the card failing to produce any output until the system is rebooted, even unloading and reloading the driver doesn't clear the error. See ivtvdriver.org for more information about this problem and possible preventative measures.

When using the PVR-250 in combination with an AVerMedia AVerTVHD MCE A180 and the Linux kernel 2.6.22, there is a i2c driver conflict with the associated tuner modules (saa7115 for the PVR-250 and the nxt200x for the MCE A180). The saa7115 module must be loaded prior to the nxt200x module or you will not be able to tune the PVR-250. MythTV will report failures to tune the PVR-250 in the backend log and the kernel will log:

ivtv0: i2c addr 0x21 not found for command 0xc0cc5605

The ordering of the module load can be solved either in modprobe.conf using the install method or by manually calling modprobe in the correct order prior to the system scripts automatically installing drivers (rc.sysinit for Fedora).

Log Messages

If you see an "Unreasonably low latency" message from ivtv in your logs you should probably read the page on PCI Latency.

Installation guides

Usually found upon install.

FAQs

Best info most likely found on the IVTV driver forum on Sourceforge. See also the wiki at: http://ivtvdriver.org/
