Local Channels stuttering.

So your not the only one. I have 3 r10's and they all started doing this around the same time. Granted 2 were activated and connected to satellite. This is where i am suspicious.

Hail/lightning storm came around bout the same time.. but no one around me has any issues with their hd dvr's or such.

2-r10's active bed,basement,
1-hr20 active- living room

bedroom r10 local channel stutters
basement r10 local channel stutters
craftroom r10--network only----activated week later to see if it was having issue and it is doing it also.
Directv came out swapped my multiswitch and changed me from 5lnb to 3lnb. still does it.
Occasionally the hr20 stutters on locals.. RARELY per the kids when we watch it in living room.

So i took my r10's out to someone elses house bout 45 mins from me to test with his sat/switch and it stutters there also.

This is def something with the sat tuner or feed, It is not the hard drive.
I had the orig harddrive from one of my r10's.(over5yrs old i think) and powered up and it stutters on locals..either tuner.

Then I took my dads RCA DVR80 and activated it, it does not stutter (non-modified)

so I was pegging this as a sat tuner issue on 2 of my units and thinking my 3rd r10 that was network only must have took power spike(makes no sense) .
So i am thinking of just getting some new rca dvr's and mod them long as they work.

I think i will need to post this on DD site also but surely we are not the only 2 having this issue.
So my plan is get new dvr or just punt it all and go net streaming. since the new dtivo is not gonna be out for ever.

I had recently done maintenance on my three DSR708's. Replaced 6.4a on the living room one with zippered 6.2a, and then started noticing the 'stuttering.' Thought it was my problem, started doing testing. (didn't watch a lot of local channels on the other two 708's) Eventually saw this thread.

Now I have put a stock instantcake 6.2a on one DSR708, put original 6.4a disk back on the LR one, and left the hacked 6.2a (ptvnet and enhancement script) on the third. Have a variety of disks to use, ide's and Sata with the JMicron chip adapter. Right now, all 708's are on IDE drives.

Watching predominantly the 'Today' show for testing.

Stuttering occurs on both stock and hacked 6.2a, and does not occur on the 6.4a (no hacks). Recorded CNN during the same interval (7-11am), and do not see it there.

As reported before, it seems to occur when the network throws it to the local NBC5 Chicago station before 30min and before the hour. When the local NBC5 video appears, a blip usually occurs in about 15 seconds. Then maybe a couple more. Also seem to notice that if a 'new' video source occurs, say a local commercial, another blip may occur in 15 seconds. Not always. No blips seen during Today network feed.

Also occurs on other local channels. Best I've captured is channel 23, WWME Chicago, on a Twilight Zone promo at the beginning of a Mary Tyler Moore show. The Twilight Zone music goes: "dee-uhh-dee-dee-uhh-dee"

As I said in previous post, I'm in a Chicago condo served by MDU Communications running a stacked system. The 708's have run fine for years. I also have a HR20I connected to Directv's MFH3 system delivering HD over phone wires using a vdsl modem. No blips seen on 'Today' on the HR20I.
Note: I am recording the SD feed on the HR20I.


Another tenant has stock R10's running 6.4a and I do not see any similar blips on the 'Today' show there.
I am willing to try any more tests and or hacks. Have Winmfs backup of 6.4a, zipper cds, ptvnet, and instantcake 6.2a. Also have a few spare 708's and R10's

Interesting and annoying problem.

This is still occurring on my 6.2a dsr708's (one hacked, one unhacked). Still not occurring on my 6.4a (unhacked as of yet) dsr708.

When the local Chicago NBC5 station takes over before the half hour and the hour on the Today show, the closed captioning has to change from national to local. They even run an ad that local closed captioning is sponsored by Luna carpets. When I turn on CC, I can believe there is some correlation with the stuttering. Don't know how the cc switch occurs, but sometimes I see the cc end prior to the locals coming on, and I see the stuttering around those times. So, I have seen a stutter on the network just seconds away from what I think is a switch to the local.

Can closed captioning or other vbi information be involved?

Could some equipment at the local Chicago uplink of Directv have changed to cause something because of some 'ragged' switch? You'd think this is all accurately synchronized at NBC5 and the directv uplink would not see any kind of disruption.

And why would it occur on 6.2a and not on 6.4a?

Is there way to analyze the tivo files to identify the stuttering?

Searching shows a tivovbi app. Could that help identify anything?

Maybe also capture the output video on a video capture card for analysis?

Is there anyone in Chicago on 6.2a *not* seeing this stuttering on the locals?

I'm willing to keep testing if anyone has some ideas. Otherwise should we abandon 6.2a for 6.4a?
