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-
Connector)
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
Characters
over the decoded Video-Frames.
More differences between 'use PVR-350 MPEG Decoder' and 'not to use it'
are:
- 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
clear
what happens 'behind the scenes'
