[mythtv-users] Back-toBack recordings from the same source

[Pieter De Wit]

Hello List,

This might be a dev list question, but here goes:

Is there a way to tell Mythtv to use the same source for back-to-back 
recordings of programs, with overlapping start and finish times ? (what 
a mouth full :) )

Let see how my ASCII art skills are:


------>time

--->(1)--->(2)--->(3)-->(4)--->(5)--->

1) Start of "P1" recording
2) Real start of "P1"
3) Start of "P2" recording
4) End of "P1"/Start of "P2" following 1 or two ads (In New Zealand, 
zero ads between programs on some channels, there is title scrolling and 
all that)
5) End of "P1" recording
--> Live goes on

I have found it *very* hard to get the over-recording right (I think 
they call it "island time" :D ). The best way for me is to set the 
pre-start recording time to 120 seconds and over record by 300 seconds. 
The problem this causes is that "all" my tuners are busy (hauppauge Nova 
S Plus)

I am told this card can do up to 8 recordings (via that magic that Myth 
does) but I could have sworn the last time I set it to 8 the quality 
went down (the picture appeared snowy) If the card is happy to handle 8 
decodes, then that solves my problem, but what about people that arn't 
that lucky.

Here is what I thought could happen:

At 3) - create another ring buffer that "feeds off" the already created 
ring buffer for 1)
At 4) - release the ring buffer for 1)
At 5) - release the ring buffer created at 3)

I hope that makes sense, comments/flaming welcome

Cheers,

Pieter
