Comment(by oli.henning at web.de):

 I was the original poster of this Bug. My Hardware is:

 Hauppauge PVR-350 with TV-IN and Video-Out (MPEG Encoder AND Decoder)
 TV connected to Video-Out of PVR-350
 X-Window-Driver configured to use Video-Overlay of PVR-350 (für Menus,
 Pictures etc.)
 MythTV configured to use PVR-350 MPEG Decoder (so it uses the Video-Out of
 this Card)
 Nothing connected to my 'normal' On-Board-VGA-Graphics.Card (15-Pin-VGA-

 With this configuration i can have no Videotext (neighter on Live-TV nor
 on Recorded Shows)

 '''But:''' When i disable the 'use PVR-350 MPEG Decoder' feature, then the
 MPEG-Decoding is done by the CPU and the decoded video is rendered via the
 X-Window-Driver (=Video-Overlay). With this configuration '''I HAVE
 VIDEOTEXT''', both in LiveTV and recorded shows!

 This makes sense, as the MPEG nor streams through the MythTV-Software,
 which can
 decode 'in a magig way0 (megic für me) the Videotext-Date and 'render' the
 over the decoded Video-Frames.

 More differences between 'use PVR-350 MPEG Decoder' and 'not to use it'

 - With Software-Decoder i can use 'increase playback speed'. With
 Hardware-Decoder this isn't working

 - With Software-Decoder i can use Zooming

 - With Software-Dcoder i can use the Aspect-Ration-Switching

 perhaps there are more differences, but this should be enought to make
 what happens 'behind the scenes'
