Position.z and Cardata.z HELP!!!!!!!!

[dusanpavl0vic]

Hi everyone,
I'm working with the F1 live timing API (Position.z and CarData.z streams), and I'm having trouble decoding the data correctly.

I'm decoding the Base64 string and using zlib (raw deflate), but the output I get always contains:

Status: "OnTrack"
X: 0, Y: 0, Z: 0

for all drivers.

Am I doing something wrong in the decoding process, or is this expected for some packets?
Is there anything specific I should watch out for when parsing these .z streams?

Any help or example would be really appreciated!
