Hello,
I've been searching for a solution to this for a while. I've been
using closed captions with Mythtv and my PVR250 since it started
supporting that option. After I upgraded to ivtv version 0.10.1, I get
extreme losses in the captioning, somtimes 5 to 10 letters are missing
from the sentence. I've even updated to the latest Fedora kernel 2.6.22
and IVTV version 1.0.0 and it is still a problem.
If I got back to IVTV version 0.10.0, then the captions work OK again,
but then my lirc_serial homebrew remote receiver has major repeat issues
while capturing.
I don't think it is a Mythtv problem, because I can watch shows recorded
with pre 0.10.1 and it plays it back OK. also, files recorded with cat
/dev/video0 > test.mpg have the same problem when played in mythtv.
here's my dmesg output.
