I tried with the CVS drivers, and it seems to work a bit better:

# czap subtv
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
  8 subtv:290000000:INVERSION_AUTO:5900000:FEC_NONE:QAM_128:353:609:97
  8 subtv: f 290000000, s 5900000, i 2, fec 0, qam 4, v 0x161, a 0x261
status 00 | signal 0000 | snr 0000 | ber 23000000 | unc 00000000 |
status 00 | signal 0000 | snr 0000 | ber 23000000 | unc 00000000 |
status 1f | signal 0000 | snr 0400 | ber 23000000 | unc 00000000 |
FE_HAS_LOCK
status 1f | signal 0000 | snr 0400 | ber 23000000 | unc 00000000 |
FE_HAS_LOCK
status 1f | signal 0000 | snr 0000 | ber 23000000 | unc 00000000 |
FE_HAS_LOCK
status 1f | signal 0000 | snr 0400 | ber 23000000 | unc 00000000 |
FE_HAS_LOCK
status 1f | signal 0000 | snr 0400 | ber 23000000 | unc 00000000 |
FE_HAS_LOCK

So, next step is to find some software renderer, as this card doesn't
have hardware decoder...
