[vdr] How is the length of a recording calculated

["Sameer Khosla" <sameerkhosla@rogers.com>]

Hi, I don't know if this question has come up or not, or even if the PAL
users experience (since I am guessing this issue only affects NTSC users),
but I am wondering how the length of a recorded file is recorded.

The reason I ask is that with the NTSC sources that I record, the reported
time for the recording is *always* longer.

For example, if I set a timer to record from 8pm to 9pm, it does.  However
it reports the length of the recording to be something like 1:10:35.  

It's is not always predictable, sometimes on an hour long recording it will
show as 7 minutes longer, and sometimes 15 minutes longer, and sometimes 2.5
minutes longer.

But it is always longer.  My thoughts (which could be wrong, this is just a
guess) is that could this possibly have something to do with calculating the
length based on number of frames (where the fps is different for PAL and
NTSC).

Is there any easy way to fix this?
