The video4linux RPM provides a tuner module with definitions for some of 
the new tuners being used by Hauppauge.  If you have an NTSC PVR-{2,3}50 
purchased recently (within the last 4-5 months), you may need the V4L 
RPM.  If you have an NTSC PVR-150, you almost definitely need it.  Note 
that if you're using Linux 2.6.10 (or above), you won't need it.

>2) With respect to the file msp3400.ko ... which rpm provides it ? kernel-module-video4linux-`uname -r` or kernel-module-ivtv-`uname -r` (with the name msp3400-ivtv.ko). In short which file should I use ?
msp3400.ko is provided by V4L.  msp3400-ivtv.ko is provided by IvyTV.  
You will probably need to use msp3400-ivtv.ko (instructions for doing so 
are avialable in the list archives).  There has been a recent effort to 
incorporate the ivtv changes into the V4L, but as of Linux 2.6.10, there 
are still some problems with ivtv support in the kernel's msp3400.

>3) Further to question 2 what is the use of the module "msp3400-ivtv.ko" provided by : kernel-module-ivtv-`uname -r` ? 
It replaces the msp3400.ko provided by V4L and will be available until 
the one in V4L (which will eventually be incorporated into the Linux 
kernel's distribution) has been determined to be "ready for prime-time."
