With kernel 2.6.38, the DVB card is very slow zapping channels (even half a minute in vlc!). Some channels don't show at all. Vlc still plays at normal speed, but mplayer is very slow (like in a vesa mode) despite the native Intel driver loaded.
Downgrading the Xorg didn't fixed the problem. Downgrading to 2.6.37-6 restored the normal function.

I can confirm this issue. I'm using a DIGIVOX mini II V3.0 (AF9015), kaffeine doesn't tune Channels, on a channel search it doesn't find any.

An issue with the new kernel/it's modules sounds plausible to me. Though that af9013 module looks wrong to me too, I'll blacklist it and see what happens (since I can't unload it).

Alright, blacklisting af9013 did not do the trick. I rolled back to kernel 2.6.37.5-1 and noticed I had to force pacman to install the old kernel package cuz the following files were still in filesystem
/lib/modules/2.6.37-ARCH/modules.alias
/lib/modules/2.6.37-ARCH/modules.alias.bin
/lib/modules/2.6.37-ARCH/modules.builtin

/lib/modules/2.6.37-ARCH/modules.symbols
/lib/modules/2.6.37-ARCH/modules.symbols.bin
/lib/modules/2.6.37-ARCH/modules.usbmapI'm not sure why these files owned by kernel26-2.6.37.5-1 still persisted after pacman -Syu installed kernel26-2.6.38.2-1.
Anyhow, with the .37.5-1 package I can watch tv again.

Kernel 2.6.38.3-1 does not fix it. Though mplayer plays dvb fine now, xine does too.
Kaffeine doesn't seem to have a --verbose switch so I'm kind of stuck here. No idea if the error lies within kaffeine or if it is a kernel regression bug (since downgrading to <=2.6.37.5-1 fixes that behaviour). Any input is appreciated.

Kernel 2.6.38.4 still doesn't works properly. Not only vlc, but also mplayer: only non-HD channels show with slow reproduction. However 2.6.37 works flawlessly in a Pentium 4 at 3.3 GHz (despite HD channels need nearly a full CPU). Anyway, with non-HD channels, 2.6.38 doesn't uses a lot of CPU but they don't show smoothly.

Seems like we were suffering from different problems. Luckily (for me) with the latest kdelibs (4.6.3-1, hit arch repos yesterday) even kaffeine plays dvb fine again.
Hopefully you'll find a solution or at least a work around for your issue.
