I would like to acces teletext simultaneously with MPEG2 capturing on THEATRIX 550 analog TV card (ATI THEATER 550 chip).
However, when I connect the corresponding direct show filters to "ATI VBI Output" pin (see attachment) the mpeg2 bitrate of the created capture file does not correspond to the settings of "ATI AVStream MPEG2 Multiplexer" filter. The bitrate becomes very high around 14Mbps.
When no filters are attached to "ATI VBI Output" pin everything works as expected.
Similar bitrate problems occur if I use this card in GB-PVR as a standard capture device with teletext enabled. After I disable teletext it works OK.
Does anybody know wheter this is a bug? Is there a workaround for this situation?
