Yes, I have. I am actually now using 2 day old version from
http://linuxtv.org/hg/v4l-dvb which includes the FE_CAN_2G_MODULATION 
flag support in driver.

And now I am finally able to watch the
HD content with my vdr 1.7.2 and streamdev server plugin by using mplayer 
or vlc as a client with HVR-4000.

BUT there is somewhere bug in the vdr channel tuning because it seems that
if I want to watch dvb-s or dvb-s2 channels, I must first tune to correct 
channel with vdr-1.6.0 or with szap-s2...

I tried to put step by step guide/notes how I got VDR172/h264 KIND of 
working... Maybe you could get it working in similar way...

1) Build and install latest v4l-dvb drivers
2) Checkout s2-szap from http://mercurial.intuxication.org/hg/szap-s2
   (I am using couple of weeks old version), and change INCLUDE line in
   Makefile to point your v4l-dvb driver sources. I have for example
   Then build it.
3) Add hd channel info to szap2 channels.conf With astra-28.2E I can 
use following with szap2channels.conf
4) Test whether tuning works with szap2, I use

[lamikr at tinka szap-s2]$ ./szap-s2 -a 1 -S 2 -c szap2channels.conf arteHD
ERROR: invalid value for parameter ''
reading channels from file 'szap2channels.conf'
zapping to 1 'arteHD':

vpid 0x1842, apid 0x1856, sid 0x0000

status 1f | signal c2c0 | snr 8b33 | ber 00000000 | unc 00000000 | 

(I could then try to record and watch from command line by using commands:
# dvbstream -c 1 8192 -o > test3.mpg
# vlc test3.mpg

4) Extract vdr-1.7.2 (I have cloned from unofficial vdr git repo)

5) Apply attached 2G modulation support patch for vdr-1.7.2 (due to flag 
name change in official V4L-DVB drivers)
patch -p1 < ../vdr172_v4ldvb_2g_modulation_support.patch

6) Apply h264 support patch for vdr-1.7.2 that has been earlier send to 
mailing list:
patch -p1 < 

7) download and configure latest dvbstreamdev plugin from cvs
- update plugins/streamdev/streamdevhosts.conf
- update svdrphosts.conf
- update runvdr
(VDRCMD="$VDRPRG --lirc -w 15 -c 
/home/lamikr/dvb/vdr/vdr-git -Pstreamdev-server")

8) Include arteHD info to top of the vdr channels.conf

9) Make sure you have tuned to arteHD with szap-s2 and then closed szap 
(see step 4)

10) launch vdr 1.7.2 with runvdr

11) watch arteHD with
vlc http://localhost:3000/TS/2

If I now would like to watch arte instead, I would need to close vdr, 
szap first from command line and then re-launch vdr...

Btw... I now really envy the vdpay/nvidia cpu usage as with 780G 
motherboard I have...
