Terratec Cinergy hybrid T USB XS (sic!) DVB-T support on Linux

Amasingly, the em28xx driver just works! At least with kernel 2.6.24.6. But the user-space tuner driver is currently not available.

The signal strength of DVB-T seems to have improved over the last time I tried (one year ago). Now I can even watch TV without moving the antenna close to the window

Here are the transponder settings for Austria (as they come with Ubuntu 8.04):

T 490000000 8MHz 3/4 NONE QAM16 8k 1/4 NONE #K23, Innsbruck
T 498000000 8MHz 3/4 NONE QAM16 8k 1/4 NONE #K24, Bregenz
T 562000000 8MHz 3/4 NONE QAM16 8k 1/4 NONE #K24, Salzburg (w/ overspill to Germany)
T 562000000 8MHz 3/4 NONE QAM16 8k 1/4 NONE #K43, Linz, Amstetten
T 754000000 8MHz 3/4 NONE QAM16 8k 1/4 NONE #K56, Eisenstadt
T 794000000 8MHz 3/4 NONE QAM16 8k 1/4 NONE #K61, Wien
T 802000000 8MHz 3/4 NONE QAM16 8k 1/4 NONE #K62, Graz
T 850000000 8MHz 3/4 NONE QAM16 8k 1/4 NONE #K68, St.Pölten
T 802000000 8MHz 3/4 NONE QAM16 8k 1/4 NONE #K69, Graz, Klagenfurt

And the channel list I got for Salzburg:

ORF1:562000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_3_4:FEC_AUTO:QAM_16:
  TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_4:HIERARCHY_NONE:3210:3211:10101
ORF2S:562000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_3_4:FEC_AUTO:QAM_16:
  TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_4:HIERARCHY_NONE:3220:3221:10107
ATV:562000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_3_4:FEC_AUTO:QAM_16:
  TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_4:HIERARCHY_NONE:3240:3241:10120
ORF2 O:562000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_3_4:FEC_AUTO:QAM_16:
  TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_4:HIERARCHY_NONE:3220:3221:10127

CHDK on A720

The Powershot A720 is a bit different compared to the IXUS 70; it runs on Canon's own DRYOS (instead of Windriver's VxWorks), it runs on regular AAA batteries, and it loads the CHDK firmware only on boot. So one has to make the SD card bootable in order that the DISKBOOT.BIN file get loaded.

And the image sensor seems to be of higher quality.
