Abstract (from CDS):

We present further results from a high-speed photometric survey of faint cataclysmic variables. We find that V842 Cen (Nova Cen 1986 No. 2) is highly active, but with no evident orbital modulation. BY Cir (Nova Cir 1995) is an eclipsing system with an orbital period (Porb) of 6.76 h. TV Crv, an SU UMa type dwarf nova, is found to have Porb= 1.509 h from photometry at quiescence. DD Cir (Nova Cir 1999) is an eclipsing system with Porb= 2.339 h, a possible secondary eclipse, and a ∼670 s photometric modulation. V655 CrA is highly active but shows no orbital modulation. The identification of V794 Oph is probably incorrect as we find no photometric variability. CP Cru (Nova Cru 1996) is an eclipsing system with Porb= 22.7 h. V992 Sco has Porb= 3.686 h from its periodic modulation. The supposed identification of EU Sct is probably incorrect. Finally, during one run V373 Sct (Nova Sct 1975) had a 258.3-s coherent periodicity, making it a candidate DQ Herculis star.
