[vdr] AW: Re: AC3 over DVB Nexus-s Card

[Jörg Knitter <joerg.knitter@gmx.de>]

Hi, I am a newby and follow this AC3 over DVB Nexus topic with higher
interest. But there is one basic thing I don´t understand: It is a known
bug of the DVBs, that the used TI-chip is unable to output a 1:1 signal.
One bit can not be output correctly so that AC3 output is said to be
technically impossible. Some AC3-decoders seem to have a better error
correction so that they still are able to decode AC3, but this is
different from case to case. This information is from Hauppauge.
So how does the Linux-AC3 output work? Is there a certain work-around
for this bug or do the developers simply don´t know about this hardware
limitation?

Joerg

Hi Gerald,

I have a DTT2500 and AC3 through DVB (Hauppauge WinTV DVBs 2.1 Model
564)
also don´t work. But I have a digital sound signal on the digital out
and it
works with "normal" sound. If I playback a recording with AC3 I have no
sound, but still a digital signal (sounds like a digital signal at the
analog input).
Others in the list also have problems with some receivers. Posted in

Maybe they solve the problem or we have to buy another receiver.
