Yes, I can confirm hash 2fe3..., and the images were downloaded with the supplied uhd_image_downloader, what is configured like this:
_DEFAULT_BASE_URL = "http://files.ettus.com/binaries/images/"
_AUTOGEN_IMAGES_FILENAME = "uhd-images_003.008.003-rc1.zip"
_AUTOGEN_IMAGES_CHECKSUM = "8522b02386f5fe0bb51baa3ba0001ef0"
The GRC filkes are accessible now, the only modifications I made were due to Ron Economos' hints regarding sampling rate, and I added a frequency slider to choose the correct European TV channel without having to know the frequency.
I'm not able to access either of the .grc files on your website, but using the original dvbt_tx_demo_8k flow graph from gr-dvbt, the spectrum I generate with 003.008.003-RC1 has a 3dB bandwidth of about ~7.5MHz the same as your uhd_master screen shot. I don't see the truncated bandwidth of your uhd_rc1 screenshot. http://ianbuckley.net/dvbt.jpg
Can you verify please that you have UHD at the current 003.008.003-RC1 tag position git hash 2fe319d9790c7ec0bcdb9582c4fea95f3fd809b9, and that the downloaded FPGA images are from: http://files.ettus.com/binaries/images/uhd-images_003.008.003-rc1.zip
I'll need your exact flow graph if I'm to debug this anymore.

I have put it all here, flow graphs and screenshots of the flow graphs:
OK, here we go. The hotel TV was dvb-c only, so I had to do the tests
chosen dvb-t bandwidth is 8 MHz.
Adjusting the channel bandwidth in the uhd sink block from 0 to a
RC1, master seems to work.
It is a B210, but as a note, due to the up to now missing FPGA
is received without problems.
I will know more in about three hours.
