One big advantage of Mythtv is the powerful scheduling options. One of the reasons I love Mythtv is that I never have to miss a Formula 1 broadcasting anymore.
For this I use a power query. You can add one from the Mythtv frontend but a more comfortable way is to use mythweb.
Go to "Custom" and select "Power Search" as the search type.
Then you can enter you own SQL query for example:
Title: Formule 1
Search Phrase:
(
program.title LIKE '%Formule%1%' or
program.title LIKE '%Formule%I%' or
program.title LIKE '%Formula%1%' or
program.title LIKE '%Formula%I%' or
program.subtitle LIKE '%Formule%1%' or
program.subtitle LIKE '%Formule%I%' or
program.subtitle LIKE '%Formula%1%' or
program.subtitle LIKE '%Formula%I%'
)
AND
(
channel.callsign = 'RTL%4' OR
channel.callsign = 'RTL%5' OR
channel.callsign = 'SBS%6' OR
channel.callsign = 'RTL%7'
)
End Late: 60min (you don't want to miss the end of a race even if it gets delayed :-)
