I am trying to get the dvb-t tuner working with my hvr-4000 (dvb-s is 
working fine) and have tried both the latest S2 repository and the latest 
version of liplianins multiproto repository with 2.6.26 kernels.

It seems that S2 repository does not yet support DVB-T at all, am I 
correct?  At least the "options cx88-dvb frontend=1" option in 
/etc/modprope.conf prevents adapters to be created at all under
/dev/dvb. Without that option adapter is created but it can only be used 
for scanning dvb-s.

WIth liplianinis multiproto version the selection between DVB-S and DVB-T 
works by using the "options cx88-dvb frontend=1" but I am seeing the i2c
errors described below.

Could you have any URL and changeset tag to patch in some repository where 
this I2C thing has been fixed?

Btw, I tested also the HVR-1300 and it seems to be working with S2 but 
scan (from dvb-apps trunk) is failing to find channels from some 
frequencies while things with external philips dvb-t work ok.
(-5 option for scan does not make any difference)

The message I am getting with scan is.:
