If dst_algo=0 is not specified to the module, the H/W algorithm will be 
used default, which is still in testing..
to make the module run in s/w mode, one needs the dst_algo=0, 1 means it 
will run in H/W mode.

Till H/W mode is completely fixed, i will suggest that people stick to 
dst_algo=0 for normal use, people who would like to help testing the H/W 
mode can help by testing the H/W mode. That's what i meant.

The H/W mode of operation is still in development in the way that it is 
not completely implemented. I pointed you to the tree because, that tree 
has the "frontend not found" fix for you.

You should be able to get your channels list as what you used to do 
earlier. Only the tuning algorithm diffrence is there.

I think that's because it is using H/W mode and H/W mode is still yet to 
take off. S/W mode should work good as was earlier with other cards. H/W 
mode should give you a better performance in tuning once H/W tuning mode 
support is complete.
