Yeah but unlike alot of the £30/$30 ones, its not a software one.
TV tuners are like modems, there's software ones and hardware. I've
just had my first experience of a software one and it is shite. Picture
freezes everytime I fire up an app or load a new webpage in the browser
and this is on a 3.2GHz/1GB RAM system.
Unlike many softmodems (or controllerless modems) though, some manufacturers
of TV Tuner software have got things pretty sorted - as you see with
Guesswho's post earlier in the thread, its easily possible to get reliable
TV Tuner/PVR software combinations (although the opposite is still
possible - you have to be careful what you choose). I've had several ATI All
In Wonder cards in recent years and the newest versions of MMC are now
pretty good (provided it's correctly installed, strictly following the
documented installation procedures). Certainly there's none of that unwanted
picture freezing that you refer to at all. I used to have an old Provideo TV
Tuner on a machine with an S3 Savage 4 graphics card and that froze
regularly but it turned out the problem was with the graphics card hardware
not reliably supporting the required DirectX functionality. A replacement
(newer stepping) S3 Savage 4 card fixed it perfectly. Perhaps your problems
are also graphics card (or installation) related Conor?
I'd be all for hardware MPEG encoding TV Tuners if it wasn't for one
important thing - they still use LOADS of CPU power under Windows MCE 2005.
Pentium 4 3 GHz+ systems shouldn't be using 30% of CPU resources when
recording TV programs - but according to the reviews I've read they do. My
All In Wonder Radeon equipped Athlon 1600+ MP only uses 27% when recoding at
the best MPEG 2 settings using ATI's software (MMC) encoding. Given this and
the power available with current CPUs its easily possible to have dual TV
Tuner setups working together. When the TV tuners are running, often nothing
or little else will be occurring to load up the CPU. This differs to
softmodems which are often used under conditions of high CPU load e.g.
online gaming. I personally think hardware encoding is a bit of a marketing
con to suck people into believing its the only way their CPUs will be
lightly loaded and recording will be 100% reliable. FWIW I've had softmodems
and controllerless modems but now its only full hardware devices for me as
far as modems are concerned (I currently have a message saver type modem
which works independently of the PC - try that with a software modem). TV
Tuners are a different story though and software encoding these days is a
good idea and offers excellent value (providing your machine is up to it).
