With your hr44/C41 setup, does the c41 let you access dual live tuners, like you can with an HR using the down button? When you first turn it on, is the 90 minute buffer there? I like to wake up to a news channel, and then quickly rewind 20 or 30 minutes so I can get caught up on the news while skipping commercials. Lastly, is there much lag when you use trick play commands, like ff or 30 sec skips on the C41?
Yes on the dual live tuners. Hitting down twice activates it and I can switch back and forth between the two with down arrow and buffer is retained for both. Performance doing this is pretty good. Not as good as being at the HR device but not bad at all.
As for the 90 minute buffer at power on, that doesn't appear to be there, or at least is hit and miss. After powering off client I waited about 15 minutes and powered back on and the 15 minute buffer was still there. However, I tried it again, this time going to the HR and switching channels, then came back to the client and the buffer was gone at power on. Even more odd, if the buffer is active, and this appears to be the case on the HR as well, if a new show starts the buffer resets itself to the start of that show. For example if a football game ends at 5pm and news comes on at 5pm, if it was left on that channel at 4:30 and I come back to it at 4:59 the 29 minute buffer is there. But if I power on at 5:05pm there's only a 5 minute buffer. (I hope that all makes sense.) And even more interesting, if my wife is watching channel 100 and has been for an hour, and I've been watching channel 50 for 1/2 hour, if I flip over to channel 100 the entire buffer from my wife's "session" is all there. Maybe this is typical behavior, I'm a DVR noob, but thought that was kind of cool.
There's about a 5 second delay from the point of hitting >> for the 30 second slip to finish and return to normal viewing. I haven't tried skip instead of slip, guessing that would be a little faster. Slip at the HR unit is 1-2 seconds.
Other findings... Messing around with pausing live, FF, rewinding, etc at the client seems to have made it lock up a couple times. Only way to get out of it was to switch channels. I read where that happened/happens with C31 clients, not sure if that's a known issue with C41's now as well. Seems to happen at the point the buffer catches up to live TV using FF.
Also, I'm not even sure about the 90 minute buffer at power on for the HR44 itself. When I first started testing and powered it on there was no buffer, but about an hour later when I powered on there was 1 hour of buffer. It's possible the HR had gone into "sleep" mode after 4 hours, something I'm going to turn off, but I was also messing around with the client box in between so not sure if doing that nuked the buffer on the HR. Anyway, some kind of odd stuff but again I'm a noob and this may be something that just happens.
