The Pinnacle card doesn't seem to have an encode/compression chip, it relies on software to do the job, so there's a good chance your computer wouldn't be able to keep up with the video stream.
Since your main purpose is to make DVDs from VHS tape and not do extensive editing, I can only recommend what I know works, the Hauppauge PVR250. This is a TV receiver and video converter on a PCI bus card that also has an MPEG1 and MPEG2 compression chip. This means it can produce the DVD required multiplexed MPEG2 video and MPEG1 Level II audio file in real time without skipping or losing audio sync. It does come with a 'cuts only' video editor and a DVD authoring program from Ulead. I wasn't impressed with either of these and instead purchased the Nero 6 Ultra Edition, which comes with good DVD authoring and burning abilities.
As Evereddie said, the MPEG2 format isn't readily editable, other than simple cuts at I frames. (This is an MPEG compression term, I frames are frames that are complete in themselves and don't depend on prior or subsequent frames for reconstruction f the original picture.) There is a distressing tendency for any editing on an MPEG2 file to cause the authoring program to insist on recompressing the video, and this wastes time plus introduces very noticable distortion.
Now, on a practical note, if you have a 90 minute tape, expect to spend 90 minutes recording it and at least another 60 minutes authoring and burning the DVD. The authoring process requires modifying the MPEG2 file, converting it to several .VOB files along with other files DVD players require.
If the authoring program insists on recompressing, that will take another 120 to 360 minutes. If you intend on watching the movie a lot, it's worth the effort, but if it's to be watched only once a year or longer, well, I don't think it is.
