Hi all,

I'm sorry to say that I agree with Felix on that one...
We should give the user the oppertunity to choose whether he wants to view
buffered TV (with all its advantages) or or plain TV (bit streamdump from
the HW) - it can even be under a compilation flag...
What we shouldn't do is  to decide for the user how he or she are going to
watch TV.

Isn't that what LINUX is all about - freedome of choice..?

BTW: in the windows SW I got with my Hauppauge 150 I am able to view TV and
record quite smoothly.... (I can't explain it...).

If you have a way to record 4 real time seconds of video in 2 seconds

time, then please share. The lag you experience is due to the buffer

setup. Granted, this lag time maybe could be reduced. I don't know,

I've never looked at that part of the code.

That's your honest opinion. IMHO, I want to sit down and watch only

what I want to watch. I do this by recording lots of programs ahead of

time. If I wanted to channel surf, I'll use my TV, it's tuner is

better suited for that.

Um, don't channel surf and watch prerecorded shows? Or deal with the

lag. Your call. Personally, I'm happy.
