#5259: YUYV to YUV420P conversion only uses top field

 In NuppelVideoRecorder.cpp, the YUYV to YUV420P conversion is described as

 // Treat lines in batches of two, first use color information, then don't

 For interlaced content, this has the effect of ignoring one field of
 chroma information. When played back, the chroma sometimes looks like it
 is delayed behind the luma.

 Even for progressive content, this isn't a particularly good resampling
