Description

I have an Hauppauge Nova-T (DVB#0 Using DVB card 0, with frontend 'Conexant CX22702 DVB-T'.) running in a mythbackend.

I have three frontends:

  1. amd64 with ATI graphics card
  2. EPIA M10000 (CLE266 MPEG2/C3-2 Nehmiah + 512Mb RAM)
  3. EPIA TC6000 (CLE266 MPEG2/C3 Eden)

All three frontends (from 0.18 to latest CVS, I never tried older releases) take approx 12-15 seconds to change channel, when watching live TV.

Starting recordings can take ~7-8 seconds.

looking at the backend when a recording starts, it looks like the DVB card delivers data after 1 or 2 seconds. Looking at the files, they start being filled with data from about this time.

I would like to investigate this problem, but if anyone has seen it before and knows a fix.
