[mythtv] Channel change time

[James Courtier-Dutton]

Hi,

I have not improved anything yet, but this is what I have found.
1) With my DVB card, the frequency tuning is quick.
Time from channel change request to first TS packet is 711ms.
2) The ringBuffer then waits for 2028ms before it lets any TS packets
to be processed.
So, a PAT is not even processed until 2028ms after the first TS packet
from the newly tuned channel.
For this entire 2028ms, TS packets are just dropped.

I believe this is not the ideal way to do things.
Is there any reason to delay the ringBuffer initialisation at all. Why
not initialise the ringBuffer at channel frequency tune point?
I think this would shave 2 seconds off the DVB channel switch time.

Kind Regards

James
