The calls on the BWPi DVD are the same as those on the Roche CD, although on BWPI they are labelled 'flight calls and song'
I can't find anything in the description to match the call you describe, either...
Calls of Adults
(1) General contact and alarm calls. (a) Main contact call a soft but penetrating 'pweet-pweet-pweet', heard in flying flocks (P J Sellar); 'pilk-pilk-pilk' (Kapitonov 1962) or 'tititititi' in low-flying courting parties (Marra 1964). Intention-to-fly indicated by 'pit-pit'; in flight, a hard 'püt-püt-püt' (Rittinghaus 1962; Köpke 1967). (b) Take-off call (occasionally heard in full flight or on landing). A trilling 'píöööör' or 'píööö' (Rittinghaus 1962); a clear ringing repeated 'pyurrr' (Vasilchenko and Unzhakov 1977); 'pjürr' (like Dunlin Calidris alpina) and thin, high-pitched chirping 'djürredjürredjürre' (Köpke 1967a); soft 'teeur' or 'peeur' often the first and commonest call heard, sometimes 'peeuri' repeated irregularly at intervals of c. 3–5 s (P J Sellar). (c) Flock calls of migrants a ringing 'kirr-dit-dit-durrr' (Rittinghaus 1962). (d) Soft 'kwip kwip' heard from feeding flock (Nethersole-Thompson 1973; see also for variants). (e) Alarm call given by single bird or pair flying off in response to remote danger a soft, tinkling, rising 'wit-wit-wit wita-wita-wita-wee' (Nethersole-Thompson 1973); 'wit-e-wee wit-e-wee wit-e-wee' (see Witherby et al. 1940); 'whit-whit-whit' (Meares 1917). (f) Creaking-call. Likened to regular creak of unoiled wheel-barrow (Blackwood 1920); given under similar circumstances to call 1e, by bird on ground or in the air (Nethersole-Thompson 1973). (g) Ting-call. A single, sharp, explosive but rather thin 'ting', given in various situations eliciting moderate anxiety or excitement, usually from bird on ground in breeding season, e.g. when ♂ flushed from eggs; also heard in flocks (Nethersole-Thompson 1973). (h) On flushing in extreme alarm, a trill, rendered 'twrr' when bird rose at intruder's feet; similar to C. alpina (Blackwood 1920) but softer and less angry (Nethersole-Thompson 1973); also rendered as a harsh 'wer-r-r-r' (Meares 1917), 'skirr' or—less intensely—'whirr' (Nethersole-Thompson 1973), and a rattling 'tirrr' (Köpke 1967a).
