Ah, so you have tested Kevin's new baby? Is it as good as we are all
expecting it to be?

BTW, I can see you are using 031125A, this driver seems to be a good bit
less stable than 031118A for me. Isn't this so for you? Your patch works
very well with the 031118A version, with 031125A I get more freezes with
OSD interaction than with the older one. Might be a timing/latency
problem, since my HW is a bit on the low side (Epia ME6000).

I see you have a new version of the myth patch out. Is the ivtv patch
changed with this version? I ask, because I have a patched ivtv version
for download at
http://www-isl.mach.uni-karlsruhe.de/~hi93/myth/ivtv-031118A+pvr350+aew.tar.gz
which uses the last version (2 days old)
