I was thinking that switching it in and out might uncover some odd  
case in the DVB drivers, it may be that now multirec exists it's  
always "on" even for one recording per multiplex, haven't looked at  
the code, just a suggestion.

Maybe it's signal level related (some channels wouldn't play here  
sometimes, now fixed with a new aerial system last week) or some other  
system activity, I know that I get unplayable recordings if XFS is  
defragging while I have more than one recording going to a the same

Fair comment.

All looks quite reasonable to me, seems to have picked out the  
important stuff.

You could do me a big favour, post a few minutes of a couple of  
channels that work ok, I'm making some studies of encoding rates and  
standards used for sports around the world for a customer and what the  
broadcasters tell me they use often doesn't reflect reality!! Ideally  
if you can pick a little of Ten sport and something else for a  
control, that would be much appreciated.

In an earlier email you asked why I was mentioning the PS3 50Hz  
option, as you are in Aus all the transmissions are 25 or 50 frames as  
here in Europe. If your TV has told your PS3 it can display 1080p60 or  
720p60 it will play everything at 60 frames, it does an amazing job of  
conversion but setting 50Hz playback to on makes it play 25 and 50  
frame material at 720p50 or 1080p50 which is much better. If your tv  
says it can do 1080p50 (can't do 1080p60) then all is well anyway,  
well until you play something that's 30 or 60 frames! Shame there  
isn't an equivalent for 24 frames material.
