Finally I installed Knoppmyth. When installation displays this message "Knoppmyth was installed successfully". I press the Ok button. The system has to reboot automatically or I need to reboot by my self?. I type init 6 and the system reboot but when is starting the msp3410 daemon my computer is frozen. What can I do?
Thanks for your help.

Remove the PVR-xxx card from the machine.
It should now boot OK.

I just went through the same issue with mine and I am returning it to Hauppauge tomorow. I spoke to the guy at Hauppauge after installing the card in a Windows PC and it failed to load the OEM drivers, he said it sounds defective, and gave me an RMA.

I did post my troubles. I search for msp3410 would have returned my thread, thus giving you an answer . If I dont tell you to search someone else will.

if its one of the pvr 250 mce cards or a recent pvr card that has the same problem as most pvr 250 mce cards theres a problem where the ivtv drivers auto detect the wrong model of the card (diffrent chipsets)
theres a few guides and fixes for your to fix this tho if the card doesnt work in a windows box either then it may be defective but if it does then this is likly your problem so try this guide

and just change the line in it
options tuner type=45
to
options tuner type=2
45 is pal, 2 is ntsc

u can also skip the bttv steps tho if u have a bttv card in there besides the pvr card
and if i remember right the msp34xx is the sound Component for the pvr card

hopfully this helps
