... The WFPC2 CCDs have a small b ut significant charge transfer efficiency (CTE) problem which causes some signal to be lost when charge is transferred down the chip during readout. This has the effect of making objects at higher row numbers (more charge transfers) appear fainter than they would if they were at low row numbers. The effect depends on the temperature of the CCDs. ... It is also possible that proportional losses for fainter stars, at least with no background, may be larger. ...

... One of these factors is how the client application uses VDPAU; i.e. the number of surfaces allocated for buffering, order of operations, etc. ... At a bare minimum, the application must allocate one video surface for each reference frame that the stream can use (2 for MPEG or VC-1, a variable stream-dependent number for H.264) plus one surface for the picture currently being decoded. However, if this minimum number of surfaces is used, performance may be poor. ... Performance Levels . ...
