Hi,

this time a real bug report I hope smile.gif

Have an mpeg2 file, add mp2 audio from separate file. (Bitrate CBR/VBR selection does not matter)
The playback will not work when pressing the "Play O" Button. ("Play I" works)
Using a WAV file works.
Using the MP2 audio in the mpeg, it's working, too. But the audio is PCM for virtualdub, so you have to choose an external file for streaming the original data.
(The in stream audio was muxed into from the external audio before, so the data should be identical)

Mediainfo in the MP2:
Format: MPEG Audio
Format_version: Version 1
Format_profile: Layer 2
Codec: MPA1L2
Codec: MPEG-1 Audio layer 2
Duration: 5472912
Duration: 01:31:12.912
Bit_rate_mode: CBR
Bit_rate: 256 Kbps
Channel_s_: 2
Sampling_rate: 48.0 KHz
Samples_count: 262699776
Frame_count: 228038
Compression_mode: Lossy

EDIT: Wrong title. To clarify: No playback at all. Just enters Playback mode, but does not play anything.

BTW, would be nice to have a feedback on what the "autoselect bitrate mode" actually detected.
