[mythtv-users] RE: 0.18.1 DVB-S Stuttering

Hi Matt,

The problem doesn't seem to be IVTV or the LinuxTV DVB drivers - I went to
MythTV 0.18.1 from 0.17 and the stuttering appeared and then I quickly went
back to 0.17 (under lots of family pressure to get the cartoons & soaps
recording again).

But... You have to laugh... The reason I went to 0.18.1 was to get rid of
the fairly frequent frontend hanging problem (I used to ssh in and reboot to
fix it).  But it seems that the hanging was an IVTV problem because, before
going back to 0.17, I had upgraded IVTV (to 0.2.0-rc3k) and the Kernel (in
case it was a LinuxTV problem) and now no hanging ever - yippie!. 

Only thing is someone on the list did mention that the CVS version of MythTV
now automatically swaps tuners when watching TV (I have a PVR350 and a
Nexus-S) - I think I'm going to have to try the CVS version - and I'm
guessing the stuttering problem will be in the pre-0.19 MythTV version
too..... ?  - but I'll post when I try it.

I've been getting stuttering too, now you mention it!

I'm running DVB-T using Nebula DigiTV PCI cards. This was only noticed on
the weekend while trying to watch Wimbledon - very obvious and nasty
stuttering while watching tennis balls in motion. The stuttering seems to
vary depending on what is being watched, some channels/programmes "seemed"

I'm running a 2.8GHz P4, 512MB, Nebula, etc. With Gentoo and MythTV

I've not used my Myth box that much recently due to other problems with the
DVB EPG dieing on me (someone please answer my other posts to this list! ;)
But I watched a fair bit on 0.18 when I first installed that and I don't
recall any problems at all. I'm not sure of what changed between 0.18 and
0.18.1(-r2), but I'll have a look when I get time.

FYI, I've been running the same kernel version, with the same DVB driver
throughout my experience, so I'm sure they're OK.
