Hi,


I have an idea for another "nice-to-have" feature for VDR:
Some Settop-Boxes record the current tuned channel to
harddisk all the  time,

For *me*: No thanks.  Why not? Well

- You can't do a rec & inst replay of crypted channels with
   a single DVB card. This also means you can't use specific
   plugins (DVD, MP3, etc) while being tuned to a non FTA
   channel (if your idea would be implemented).
OK, I don't know, if this is true (never tried before), but if it is, You are right.


- How would you switch channels? At the moment, VDR says
   channel locked if you try to switch from a recording channel
[...]
The instant recording must be somehow different from the "normal" one, so switching must always be possible.


- Increased wear on the HDD. Whilist the disk is spinning all the time, your idea would mean the HDD is working all
the time VDR is running. Cutting a movie would become
[...]

OK. Right.

so I could "Rewind" some time or, if disturbed by someone, timeshift the missed parts.
You can already do that. Say you are watching a movie and
your friend calls you exactly when the movie suspense is
at it's highest. Just squeeze the recording button on your
RCU and pick up the phone. After finishing the call, you

Right.


* Recording should be some definable time backwards,
maybe about 2 hours

Why this? What are you going to do, if you say adjust it
for one hour and it takes you longer than one hour to get
back to the film? VDR should record as long as it takes
(and less than 23hrs 59 min ;o)).
That would fill the harddisk really soon, so just use some kind of ringbuffer for the recording.


* It must be possible to save the recording for later
viewing, so the  cutting process must be available.

??? If you record something it *IS* available. For me
VDR should *never* delete a recording automatically
(which is why my prio & lifetime are all set to 99).
If you think of the ring buffer, it must be possible to copy a part of it to a normal vdr-record directory structure for later viewing.



* Maybe start one "xxx.vdr" every 15 Minutes and
delete the old yyy.vdr  to keep the changes simple?

NO Definately not! First of all this would contradict
with your point "it must be possible to save..." What would be the advantage of deleting (which VDR doesn't
do right away anyway) a recording every 15 minutes
and starting a new one? For one thing it would clutter
up the video diretory.
No. If there is a /video/instant_replay directory, than only there are the files with the last recorded time intervalls.



What *I* never understood about this idea (you aren't
the first to mention it ;o)) is *what is it good for*????
Why do people want to buffer their stream to RAM or
HDD. Just for fear that you might miss out on 2 minutes
of the movie?
Maybe you watch something and after 30 minutes you decide, that it would be worth to save the program for viewing it again or show to your friends/family... So you could say: save this from 20:15 to 21:00 to "My Friend on TV" directory.


I agree to most of your technical points above, but still think it's a nice feature ;-)


Bye,

Dirk Melchers.
