To Juha: 
One thing is that mplayer detects but doesn't display DVB-T subtitles
(and the Finnish TV1 and TV2 channels use subtitles in a separate
stream). I've tried to hack mplayer to do so, I found some code from vdr
which does the subtitle stream decoding, but I don't understand how to
overlay the subtitle over the video in mplayer (the application is
great, but the code is a huge mess IMHO). If someone has had more
success or knows another app that plays DVB with the subtitles, I'm
interested!

Another problem, is that the transport stream that comes out from the
DVB card has time stamps that don't start at 0 when the recording
starts, so my comercial removal filter in mplayer wouldn't work. One
solution is to remultiplex the streams from TS to PS while recording,
but all the softwares I have found for that (ts2ps, mplex) don't support
subtitle streams (actually, they support 1 video stream and 1 audio
stream and that's all). So for now, only the analog TV recorded with
mencoder fits my needs.

The DVB driver 1.0.1 works quite well with my 2.4.22 kernel, but I have a
weird bug (IRQ lock or something) when I want to use the driver, so I
need to unload it and reload it before I can watch DVB TV. I haven't had
time to go deeper into this.

When I want mplayer to play DVB straight, it seems to slow down and the
video becomes jerky, or it just stops and complains about too many
errors in the data stream. If I record the stream on the disk and play
it immediately from the disk with mplayer, it works properly... I've
developed a small program based on tzap that does the recording and
supports files bigger than 2 GB (I use XFS as a filesystem which does not
limit file sizes to 2GB, but the program itself must handle large
files). I suppose I could easily use this one instead of mencoder for
recording DVB, if I add a feature to stop the recording after a given
amount of time, like mencoder does.

The last problem is that I'd like to properly integrate analog and
digital TV in freevo, so that I can choose (or use priorities to
automatically select) which tuner I use for watching/recording; I'd also
like to implement timeshift with DVB (so that I can pause the TV when
the phone rings).

Oh yes, I have no time anymore to code all this (that's why I gave up
Freevo hacking, hopefully temporarily), so if someone could lend me
some�:)

I use this feature every day. Is this enough to convice you that it's
useful? :) I completely replaced my VCR with a dedicated PC, which I use
only to run Freevo. It has no other monitor than a TV, and the keyboard
I use most of the time is the one from my IR remote control. Even my
wife uses the machine :)
