Tmpgenc questions

Having gotten back into video editing after about a year away I have a few questions...

If I record video with my PVR-250 card in DVD quality and want to cut out adverts, can I use Tmpgenc MPEG Editor without losing quality? I want to avoid any re-encoding which would result in quality loss. (http://www.pegasys-inc.com/en/product/)

Whats the difference between Tmpgenc and Tmpgenc Plus?

Thanks,

Philip

TMPGEnc MPEG Editor is a greatly improved version of the widely used MPEG Tool (included in TMPGEnc Plus 2.5). It has been reworked into a full-featured software offering fast and easy cut-editing with high precision MPEG Smart Rendering. The standard MPEG Tool could only cut on GOPs, which meant rough cut-editing. But with TMPGEnc MPEG Editor and its Smart Rendering function, accurate and precise cut-editing (at frame level!) becomes possible. The Smart Rendering technology included in TMPGEnc MPEG Editor consists in re-encoding only the necessary parts of the video, and not the whole video, allowing smooth cut-editing.

I never used the MPEG Tool in Plus 2.5. I bought TMPGEncPlus a while ago, then tytool came out for TiVo extraction and got to a point where I haven't used TMPGEnc for over a year now.

TMPGEnc is the free version, TMPGEnc Plus is the retail version, where the only difference that I remember is Mpeg2 support (trial only on the free version). I don't know if the free version has the MPEG Tool or not.
