-There is a known problem with some French channels. Because of some
-old specification interpretation mistake, some channels send the
-teletext page number in decimal coded as binary, and not as the
-standard says in hexadecimal. Since there are set top boxes sold that
-has the same bug so that they can work with there channels, they are
-reluctant to correct this. The service information for those channels
-typically say that the subtitles are on page 858 or 859 when they
-really are on page 888 or 889. To still be able to use those channels,
-you can in ttxtsubs turn on the "Workaround for some French chns"
-option which will remap numbers in the X5Y range into X8Y. Since this
-would also remap the page number for a channel that really is using
-for example page 859, this is an option that is off by default. If
-you see this problem, please contact the channel provider and make
-them understand that time will only make it harder to correct this
-mistake as more decoders with this bug will be out there and software
-updates for older set top boxes will be harder and harder to get.
-Some channels do what they can to gradually correct this by sending
-both a descriptor for French subtitles on page 859 (whish is
-interpreted as page 889 on the old non standard decoders), and as
-French for the Hearing Impaired on page 889 which is the setting that
-can be used on standard compliant decoders.
-(For the technically interrested: The hundreds figure is in teletext
-called "magazine" and is sent separately from the 8 bit "page
-number". Each magazine can actually have up to 256 pages and the page
-number is really in hex, but only the 100 pages which use only the
-figures 0-9 are normally seen by the user as only those numbers can be
-entered on the remote control keyboard. 59 hex is 89 decimal, and here
-is where something went wrong.)

Note that some channels don't use teletext subtitles but instead use
DVB subtitles, which is something different. DVB subtitles are sent as
bitmaps, somewhat like DVD subtitles. You can find a plugin for DVB
