Most of the comments and logs there provide not much help. As I told
you before, you're mixing clearly userspace issues or limitations with
kernel-related ones. For example, there's nothing we can do at driver
level to make kaffeine to perform better when decoding an MPEG-2 stream
at full screen mode. This is probably either a performance issue with
your GPU card or it is just that you're using a software decoder for it,
on a slow CPU. Some applications allow, with a few GPU types, to run the
MPEG-2 decoder inside the GPU.

Yet, there's one relevant information there:

3- And even with kaffeine, the only way that i could watch some TV, was in this manner: Before this DVB-stick i inserted another DVB-USB stick in another linux computer and scan the channels with kaffeine and after finding the channels, quit the kaffeine and copy its database files ( $HOME/.kde/share/apps/kaffeine/* ) into the testing computer for pinnacle DVB-USB hybrid stick. After that copying, i could run kaffeine on the pinnacle DVB and without scanning, thus i had a table of channels and in its main window and when i clicked on a channel, that channel was shown.

You mentioned that you did another dvb stick worked, but on another computer.
Why such dvb stick didn't work at the computer you tested your Pinnacle
device?

Also, does the working stick is capable of getting the dvb channels using the
scan tool provided at http://linuxtv.org/hg/dvb-apps? If so, please provide us
the dmesg produced with the working card and the scan results (with -v, in order
to put dvb scan into verbose mode), and the same info with the broken card.

Thanks,
Mauro
