[mythtv] Re: [experimental patch] vbi decoder for IVTV cards

[Johan Duinkerken]

Hi Martin,

Great job, this teletext/subtitle-decoder for PVR350!

I would like to give you some feedback. I'm using Mythtv17 with your
patch, on a Gentoo-system.

Initially, I got black&white teletext in a very bad quality (jumpy picture
and fuzzy text). It turned out, that XvMC was default switched "on". After
switching this setting "off", I got good, colored teletext and a stable
picture. The problem mentioned in one of the previous posts, about missing
subtitles, occurs here as well: some subtitles are there, some are not.

To be short: if you've got b&w teletext, it might be worth the try to
switch XvMC off.

Best regards,
Johan.
