something is wrong in decoding PD240 mode #74

Something is wrong only for this mode, it seems the there is a fixed amount of pixel written in a bad order in the reception buffer...or similar, i haven't read the code. Anyway, the same tx is decoded without issues using MMSSTV (i used both in the same linux machine).
Chroma odd (or even?) lines are shifted of a fixed amount, Luma one's are correct. Could you have a look? thanks.

after further investigation seems that the trouble lies in the syncDuration. If i set my encoder, to 22ms instead of the standard 20ms, the image is perfect in QSSTV (but not in MMSSTV).
