Hello all, I recently upgraded my MythTV box to Mythdora 5.0 hoping to resolve some problems I had in using MythTV. Many problems have disappeared, however... at least one remained.
When I select a TV-channel normally everything works fine, but sometimes the capture appears in black and white. When I change the channel and then return to the "black-white" channel, very often this channel reappears in full colour! The same can happen when the mythtv box records a television program. The captured video often is in black-white while at other times the capture for the same channel appears in colour. A few remarks: - Without being sure I suspect this problem appears only at a few TV-channels, i.e. this problem is not present for each TV-channel I have. - I had this problem with my previous version of mythtv (0.20). I do not know what version of ivtv was used. - In the log file /var/log/mythtv/mythbackend.log I can not see any difference in logging information whether the capturing is in colour or B/W.
