Play a dedicated Video and Audio PID in ts

[dam72]

Dear Forum,

I use the latest release of VLC. I can watch many tv services coming as http unicast (proxied from multicast to unicast). The streams are DVB-IP conform ts streams. Each stream does contain two Video PIDs, one low band quality, and one broadband quality. The Video PID of the broadband quality is always the same, 66 dec. Currently i call the stream in this syntax, http://192.168.100.21:8081/udp/234.12.134.87:1234, and this works perfectly. But how can specify the link to use always video PID 66d and audio PID 67d!?
P.S: I ask because VLC is using randomly one time the low band stream, next time broadband stream. I would like to use fixed the good quality stream.

I hope you can help me.dam72
