[mythtvnz] Use different tuner for adjacent recordings

[Aaron Whitehouse]

Thanks Tony/Steve for such great replies!

>> Can anybody think of an SQL statement that would replace all "Begin this
>> recording on time" and "End this recording on time" with 2 minutes and 5
>> minutes respectively?

For the archives, I did the following:
$ mythtv -u mythtv -p[password]
 > use mythconverg;
 > UPDATE record set startoffset = 2 , endoffset = 5 where recordid != 0;

And it seems to have worked perfectly!

Regards,

Aaron
