[vdr] DVD plugin menu and audio problems

[tho68@ssisrl.com]

Hi

I'm working on DVD plugin and I have working on two main problems

1 Using many dvd's i lost the first menu page ( I get only mark sign and
no background image)

2 Exiting dvd play, Audio from DVB is lost  until a channel change


Debugging problem 1 i get this results :

Background image is correctly loaded from dvd, is sent to DVB drivers
( transfer of the image cause a short disturb on the audio ), but is not
displayed.
I avoided this by skipping the play of the audio packet received before
the background image is transferred to the DVB drivers, in this way
i lost some audio at the beginning but menu's appear correctly.

Debugging problem 2 i get this result :

If i play a dvd and stop it before any audio is sent to DVB (
usually the initial anti piracy disclaimer is shown with no sound) ,
audio come back correctly in DVB mode ( tv channels watching ).
As soon as first audio packet is sent to DVB drivers, audio is lost
when stopping dvd play.

Comparing DVD vs VDR Recording replay. it seems DVD  plugin behave
correctly.
When stopping a DVD play , setting of the filter on the audio PID
does not fail ( return value is OK ) but audio does not flow out the same.

My questions are :

May be the problem is inside audio handling of DVB drivers ?
Have other users the same problems ?
Where I can find detailed specifications about DVD's architecture?
Where I can find detailed specifications about DVB's drivers architecture?
