I have a similar problem (input/output error on /dev/video0) with a new 
Dell Dimension 4600. I bought it especially to become my MythTVBox:-(
HW:  Intel 82865G chipset, P4 2.8Ghz, 256 Mbyte RAM, 120Gbyte HD, on 
board graphic card and a PVR350 card.
SW: Mandrake 9.2 + MythTV 0.14 + ivtv 0.1.9
I followed all installation instructions (good work by the way!)

After doing
modprobe ivtv
modprobe tuner type=28  (this is correct in my case)
test_ioctl -u 0xff  (PAL, ok in my case)
test_ioctl -p 4
test_ioct; -f width=720,height=576

cat /dev/video0 > test.mpeg

results in an input/output error

The card IS recognized; I checked this with lspci that lists
....
Multimedia video controller: Internext Compression Inc iTVC15 MPEG-2 
Encoder (rev 01)
....

A couple of months ago I tested  exactly the same setup (PVR350, myth 
0.14, Mandrake 9.2) on another 3 year old PC (Celeron 733 - no clue 
about chipset at this very moment) and that worked as a charm.

Can anybody confirm problems with this Intel chipset? Any advice? I know 
how you must be feeling; I am starting to feel very bad I spent all this 
money....

Thanks!
Johan

PS
I cannot confirm whether the combination PVR350, Windows XP and my 
chipset work. I was too quick in erasing XP and installing Linux!
