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