I took a quick look at the second sig, and the length field of the signature for R-value:

Code:
    30: OP_SEQUENCE_0x30:    type tag indicating SEQUENCE, begin sigscript
    45: OP_LENGTH_0x45:      length of R + S
    02: OP_INT_0x02:         type tag INTEGER indicating length
    21: OP_LENGTH_0x21:      this is SIG R (33 Bytes)
        00D2F9171FDCE547:34818BC6314389B2
        D7CCE4C15CC6FA55:6B3886860E493B1A
        02
    21: unknown opcode

I can see a double zero is there, so the length of the R-Value should be 21hex, 33 bytes decimal. In you case it would end with "02".
However: the 02 should be the  type tag indicating length for S-Value, and 21 the length for your S-Value (which it is...).
I just added a "DD" into the end of the R-Value, then it decodes correctly:

Code:
    30: OP_SEQUENCE_0x30:    type tag indicating SEQUENCE, begin sigscript
    45: OP_LENGTH_0x45:      length of R + S
    02: OP_INT_0x02:         type tag INTEGER indicating length
    21: OP_LENGTH_0x21:      this is SIG R (33 Bytes)
        009E38F007CCC1D4:11E9DBA6E03A932E
        E5076E2F7F4FA6C3:8B9FA6AD97265546
        DD
    02: OP_INT_0x02:         type tag INTEGER indicating length
    21: OP_LENGTH_0x21:      this is SIG S (33 Bytes)
        0099F89638981D46:5629E65C02BC5FA3
        8FB9CA49E2D3FD9F:83326CE8678195AC
        16
    01: OP_SIGHASHALL:       this terminates the ECDSA signature (ASN1-DER structure)

So I guess the library you are using is not assembling the signatures correctly. What are you using?
