I see similar behaviour for my PVR250 recordings/playback using PAL system:: cat /dev/video0 >test.mpg contains all VBI embedded packets. in mythtv, livetv recording/playback, I noticed missing VBI packets (slow teletext page updates and missing 888 subtitles). Analysis on bit-level of the recorded mpeg stream shows me that the embedded VBI packets are missing in the file, so its not the vbidecoder in mythtv.
