File format for digital TV cards

My digital tv computer external card seems to have packed it in.
I'm wondering what the file format other brands from my own (DNTV
Live) record in, and if they all do dvr-ms format.
I've noticed that if I record in mpg format, then dvds I make can get
the audio out of sync, which doesn't seem to occur with dvr-ms
converted to mpg.
I'm thinking of getting a Leadtek USB 2.0 PalmTop DTV 200H DVB-T.

I want to record in dvr-ms format in Windows XP.
I can't find this information form the web searches I've done.

My Compro 300t card can record in .mpg without problems. I suspect you have
a slow computer that can't handle the data stream, and skips frames etc,
producing out of sync recording.

I don't use the dvr-ms (Microsoft proprietary video and audio file
container format), as I don't use Microsoft media centre.

I don't even use the dodgy software that came with my TV card. One of the
best scheduling software I've come across is "DV Scheduler" , its
_freeware_, get it from this Sydney university site
(http://www.cs.usyd.edu.au/~efax/DV%20Scheduler.html).

It uses your web browser and VLC media player, to view and record digital TV
. It can even record multiple channels at the _same time_ , if they're all
from the same station. I.e. you can record nine and GO!, or ABC1 & ABC2 &
ABC3 all at the same time.

It seems to grab video stream direct from the card and write it straight to
the hard disk , saving you CPU, which is good if your computer is slow.

It records in a few formats like .mpg, and .ts (transport stream), and you
can also record HD (high definition ) if you have the disk space.

I've also used it with an el-cheapo Chinese no-name-brand USB 2.0 DVB-T,
works no problem.

You have to run a separate program to grab all the program scheduling
information (EPG) . Once the schedule is populated (it even has all the
Australian freeview TV logos) it's a breeze to set it to record single or
re-occuring programs. (http://www.cs.usyd.edu.au/~efax/DVPiper.html)

I can record in mpg without problems. When I go on with the processing
and make a DVD from it, I might encounter sync issues. Thanks for the
opinion on my computer. I prefer to take the dvr-ms files, convert to
mpg, then demux, then author the dvd.

I wanted to know if they can record in dvr-ms. I have nothing of
Microsoft media centre. So you are saying that you could record in
dvr-ms with your card and software I take it.

Having said that my Home theatre Pc is only a Pentium 4 2.ghz with ~768mb of
RAM, which is not fast compared to latest machines.

The main problem I think is the software that comes with the cards are not
well designed and are CPU/Memory hungry and interfere with the recording by
slowing the PC down.

When I was evaluating Microsoft media centre 2005, I noticed it recorded in
dvr-ms files, but I didn't like media centre overall, as there were
restrictions with DRM and limited files you could play back etc.

Dvr-ms is also MPEG-2 in a Microsoft proprietary wrapper, and apparently
being phased out for a new WTV format, see
http://en.wikipedia.org/wiki/DVR-MS .

I'm just trying to find what happens with what I can buy. If it was
only .wmv I wouldn't be surprised.

You might find also that the temporary files used for timeshifting are
in dvr-ms file format, even though they might say .tmp. I can't open
and play a .mpeg file while it is being recorded which I can do with dvr-ms.
