I just looked and some recordings are smaller now,
I have 4 recordings for Castle, all 1 hour and 5-6Gb each
7 Recordings of Eastwick each 1 hour and 5-7Gb
6 recordings of Fringe 1 hour each 6-8Gb
Going through a bunch more I find they mostly run 5-8Gb. Those are channels that do 720p where doing 8+ before when I looked. Don't have any form NBC right now which uses 1080i and was running 13Gb

Wouldn't work very well with HD video. Our locals (ATSC) use 8-13Gb/hour

1) RAM is cheap now days. Can I use RAM to keep buffer data?
(System running from USB stick so only reason to start Hard Disk is when
use recordings)

2) Patch only record current channel. It would be nice if i can select
channels from lists where buffers are active.
Example. i change channel and noticing that program what i want to look
already running so i simply press "jump backward" button and start to
program from beginning.
(2GB can keep about 100 minutes in buffers. If i select 5 different
that i got 20mins buffer in every channel)
There was some talk a while back about implementing a live tv buffer
into VDR.  Many users don't like the idea of their harddrive recording
24/7 so it was mentioned to be able to buffer to ram just as you're
asking about.  I personally do NOT want to buffer to harddrive,
especially non-stop.  However, I'm all for buffering to RAM since it
_is_ very cheap these days for 2-4GB.  I don't know how much of a
priority this is to Klaus but I'd recommend searching the mailing list
for that thread because he did participate in the discussion.

On the contrary 2-4GB should be just fine for typical live buffering
use.  If you want an hour worth of HDTV buffering you're probably
better off setting timers to record the shows you want but regardless
you can just add more ram to support more buffering time.  Btw, I have
several hour-long HDTV recordings and none of them go over 3GB.
