Yeah this does fix the problem. Its not exactly an ideal solution but I
dont use the teletext so its not a problem for me. I would be interested
in knowing if this is a bug with myth tv.
It did cross my mind that that it is to do with the signal strength
which would explain how it only effects certain channels. I use a
portable antena not a one fixed to the out side of the house. I have
noticed that when using zapping occasionally a few corrupt charciters
appear in the teletext window. Some times these also apear when the
subtitles are writen out to the terminal by mythfrontend. Its justa
thought any way.
Thanks for your help.
