According to http://linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-4000
and more specific:
Multiple frontends are supported: DVB-S/S2 and DVB-T appear as 
/dev/dvb/adapterN/frontend0 and /dev/dvb/adapterN/frontend1 respectively.

Due to a hardware limitation, the two frontends cannot be used 
simultaneously. However they can be used sequentially within the same 
application. The driver handles the mutual exclusion appropriately.

DVB-T and DVB-S are supported within API v3.2 (or the new API v5.0) and 
so it is compatible with current applications. DVB-S2 is accessed 
through API v5.0, also known as S2API, which was released in kernel 2.6.28.

and:
sage with MythTV

Some programs such as MythTV v0.21 don't know about multiple frontends 
yet. The following workaround may allow you to use both frontends however.

mkdir /dev/dvb/adapter1
ln -s /dev/dvb/adapter0/frontend1 /dev/dvb/adapter1/frontend0
ln -s /dev/dvb/adapter0/net1 /dev/dvb/adapter1/net0
ln -s /dev/dvb/adapter0/dvr1 /dev/dvb/adapter1/dvr0
ln -s /dev/dvb/adapter0/demux1 /dev/dvb/adapter1/demux0

This problem (reported as MythTV ticket #5061 ) may have been fixed by 
MythTV changeset 17832

The date of the change (16/07/2008) is after the release of MythTV v0.21 
(08/03/2008) so this is only available in SVN so far. Can someone 
confirm or deny that it works?

Note that as of June 2009 MythTV still does not support S2API. See 
ticket #5882.
