 Priority:  major                   |   Milestone:  0.19

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.
