what do you mean switch to another channel?
All channels have the same config.

I think i have a similar problem with the audio...I opned a thread to report it.

Hi.
Oor local (Israel) DVB-T channels configs are:
Video: h.264 (mpeg4)
Audio: AAC + V2

When I play the channel with your program, the audio lags (video is before the audio) and interrupts (every 2 seconds there is no audio)
