Summary: lame 3.9.2+3.9.3 put dummy data in front of 1st mp3 frame ?

Initial Comment:
Hello, I'm involved in the developement of an mp3
player - and this has problems with lame 3.9.2 and 3.9.3.

This is of course my problem - but why does the lame
encoder add additional data that seems neither to be
ID3 nor mp3?

The file begins with 
49 44 33 03 00 00 00 00 0f 01 54 49 54 32 00 00 00 11
00 00 00 43 61 6e 27 74 20 4b 65 65 70 20 49 74 20 49
6e 54 41 4c 42 00 00 00 13 00 00 00 43 61 74 63 68 20
42 75 6c 6c 20 61 74 20 46 6f  ...

which is a ID3 tag,

has then some data that seems completely random to me
- and I expect this to be the cause for my problems
(the 51 is at 0x78b):

...
00 00 00 00 00 00 00 00 00 00 00 51 01 85 c6 1c a1 18
55 d0 00 70 ec 43 ba 91 00 d4 17 61 e4 c5 44 c6 86 eb
d5 41 54 8a fe 72 d6 90 ce 12 30 31 25 35 8c 6d 70 ab
d9 89 eb 53 0d c6 fb 75 25 b9 73 f3 f3 3e de 42 20 53
8e f8 66 cb e2 aa e4 59 d2 22 94 bc f8 dc 6d 73 f3 2d

14 f4 00 b7 a9 37 ec eb cf fa 00 40 5e 48 c8 b6 03 e0
5e ...

and later starts the first mp3 frame (at 0x9ca):

ff fb b2 04 63 0d 04 19 42 3f 93 06 1b 72 80 8f 08 11
ac 0c 00 10 35 c2 fe 4c 18 63 4d 89 c8 1c 17 39 80 00
b1 51 c9 e8 8e e5 e6 45 39 93 e6 7e 51 53 52 22 d6 53
a6 db 48 b9 fc 2f e9 a6 b0 d2 17 c1 01 ...

Thanks for any hints,
Regards
Andreas (and...@3s...)
