[vdr] Stream conversion from DVB-T buggy on VDR (all versions?)



Hi,

Thanks Klaus and all supporting forces behind him for a great software,
which needs minor adjustmens to being a perfect one.

I have had problems with versions 1.0.9 + DVB-newstruct and latest 1.1.20 +
DVB 12.08.

The problem i believe is, that when DVB-T NOVA (budget) is used as a input
(can be others aswell) and output is set to DVB-S with or without recording
the stream is converted in some way incorrectly.

With DVB-T Nova the picture is perfect in non-moving parts and blocky on
moving parts. Also moving objects leave blocky trail behind. All blocks are
removed on next I-frame. Slight movement is NOT blocky, which might indicate
a buffering problem.

The stream which I inserted to a /video directory and played with VDR 1.1.20
is displayed perfectly with audio in sync. Recording was made with Windows
using DVB-T Nova.

When I create a sheduled recording and change to a different PID, on same
frequency, when VDR starts recording the stream is recorded perfectly. I
even can switch to that channel and image remains perfect while recording
and timeshifting it back and forward. If I record the current channel
with/out timer the result is, that I have problems on stream mentioned
above.

I believe, that locating is simple with minor code modifications.
1. Record stream directly without modifications to it.
2. Convert and output the stream to DVB-S (ringbuffer used for this?)
3. See weather the stream is perfect on recordings, even the screen output
is buggy.
This would indicate problem directly with stream conversion.

I may be wrong about stream conversion, if there is none I still believe,
that whatever is responsible of reading->writing the stream to other sources
is some how buggy (ringbuffer?).
