MFX_ERR_INCOMPATIBLE_VIDEO_PARAM with MPEG2 Encoding and low Bitrate

I experience an error:

  MFX_ERR_INCOMPATIBLE_VIDEO_PARAM

while calling <MFXVideoENCODE_Init> if mfx.TargetKbps is below a certain value. Settings are appropriate for regular DVD Video PAL, MPEG2.

Values for TargetKbps above 0x0120 (means ca. 4500 MBit/sec Video) give MFX_ERROR_NONE, values below result in the error code above.

Is this a bug or do I have change other settings as well?

yes, I tried to switch from

 MFX_PROFILE_MPEG2_MAIN@MFX_LEVEL_MPEG2_MAIN

to

MFX_PROFILE_MPEG2_MAIN@MFX_LEVEL_MPEG2_LOW

MFX_PROFILE_MPEG2_SIMPLE@MFX_LEVEL_MPEG2_MAIN

MFX_PROFILE_MPEG2_SIMPLE@MFX_LEVEL_MPEG2_LOW
 

but makes no difference.
