I'm seeing quite a few A/V sync problems with UK DVB-T, using vdr-1.3.12
with either CVS or ancient DVB drivers and a dxr3 for output.

It seems to be much worse over the past month or two and worse with the
BBC channels (or seems to be). The audio always ends up in front of the
video and I have to pause or skip the recording to get it to resync.

I'm also seeing a lot more glitches on these channels than I used to
(may just be vdr trying to resync, I suppose). I remember it giving
almost perfect performance.

Has the BBC (or whoever) changed anything in what they are transmitting
which is breaking sync?

Cheers,
