I would personally recommend Adobe Encore. But then I would as it's the one I have and the only one I know
Actually I though I;d already posted a reply to this question. Is it a double post? Anyway, if it;s some TV recordiong and it;s a one-off effort then downlaod and install the 30 day trial of something (Encore?) and then bash them all out.
I'm not sure what you mean by TV quality DVDs. All DVD authroing packages will be at standard PAL/NTSC resolutions so you'll always get the right level of quality in that sense. Encoding quality may vary slightly. The biggest issue you havew, quality wise, is the quality of your source material. If it's not up to scratch then neither will your final DVD be.
But basicvally, there's plenty of DVD authoring packages around. Play with a few trial versiosn and see which suits you personally.
