[confirm] Slow FM Radio channel changing (1 Viewer)

It's a known bug.
Start FM radio takes about 10-12 seconds.
Switching channels takes about 7-9 seconds.
This happens only with analog radio.
Dvb radio is perfect (1-2 secs).
Just a bump to let you know (especially mm1352000) that it doesn't depend on drivers (cards with Philips 716x chipset), because channel changing is very fast (1-2 secs) on Npvr (yet GbPvr).
So it's definitely a Mp problem.
Thank you,

    Hi sdf

    We're aware of one issue with switching between FM channels. This is caused by the fact that FM radio is detected as video. The slowness for starting and changing channels could be caused by the same problem. If the TsReader/MPFileWriter buffers are set to the appropriate size for video (rather than the size for radio) then it will take longer than it should for radio to start. We're discussing how to fix this internally, but it may not be easy and the fix may not make it into 1.2.0b...

    [Edit: I'm not 100% certain that the issue is that FM is detected as TV, however I'm reasonably confident...]

    Ok mm1352000,
    It was only a "bump" to the developers.
    Didn't know you were aware of the problem.
    Thank you,
