timeshift record problem

I have a problem with the recording function. The problem is that I can not obtain a synchronous registration when i move backwards the cursor in the timeshift bar, although the "Synchronous record" mode is enabled.
Is it only my problem? I use ProgDVB 4.91 - ProgDVB 4.85.3 and earlier are OK. Why?
Thank you.

Please click on the clock icon placed at the bottom-right of the program window...

"Synchronious recording" option in "timeshift buffer status", that's what he is talking about.

No answer? So, I put the question in a different way: what's the use of the "Synchronous recording" option in the "timeshift buffer status"?

AFAIK, you can select recording either from input (direct) or output (delayed) of the timeshift buffer.

Thanks for the answer.
The problem is that the [start-end] time of the recorded file is not accurate, if I use the timeshift.
To better understand what I mean please do this test (whith "synchronous record" on):
-start ProgDVB
-wait 1-2 min. for the filling of the buffer
-put back the cursor of the timeshift (to the start or in the middle, it's doesn't care)
-now try to record a 30 sec. TV spot.
Close the program and watch the 30 sec. recorded file. Does it correspond to what you tried to record? In my case, the answer is no.

ProgDVB is not mpeg2 editor and accuracy not very high...

When not using timeshift, ProgDVB records pretty precise.
Then, cutting with an external application is not really hard. I am always recording several minutes before and after an event, to be able, to cut perfect later on.
However, if you are watching over timeshift, you will always have to wait until the buffer minimum is filled.
If you want to record from the shifted signal, it's highly recommended, to provide a second physical HDD (not just partition), to place either the timeshift file or the recording on. Else your disk will be extremely busy, resulting in a lot of possible trouble.
If using timeshift in RAM, you MUST have pretty much of that, to 100% avoid swap file use.

I always use timeshift in RAM, this is more efficient and the HDD is not busy for this function.
@ Prog: I don't require editing features, only a good working recording feature.
Since ProgDVB offers recording features, I'd like it were the most accurate possible.
I don't understand why recording during timeshift view has not the same precision of recording in direct view.
In my opinion this problem could be fixed working on the code of ProgDVB. Is it possible?
note: In ProgDVB 4.xx ther's an error in the "timeshift buffer status": in the word synch_onous the "r" is missing.
