Fuji-film and DVD Recorder problem..

[Soccerman77]

I have been using Fuli DVD+R for the past year since I got my recorder, last week I bought a 50 pack from Best buy for 12.99.

I have 5 football games on TIVO that I would like to get on DVD. I usually do 2 hour mode, with a half per DVD for quality.

Lately, the DVD's have been recording until like after 1 hour then they would stop recording, why? When I stop them and go back to the menu the menu screen is all green and lines going through it, does this all mean a dirty laser? Should I switch DVD's quality to Sony DVD+R? When a disc isnt in the player the menu screen is fine, but after a DVD it become all green and liney.

How do I find out if my DVD is bad before I try to copy on it?

Update, I would appreciate any help...

I had the Cable Box on the DVD Recorder..

Well I moved the Box off the DVD REcorder, Cleaned the Laser, Switched Media. Now tonight I tape the Pens-Isles game, it freezes after the 1st period, that was on my old media, so tonight I want to copy my TIVO of the Pats game, so I use the older media, all is good, until :08 second left in the first half and it freezes, so I try the new media and it freezes right away.

One thing is that there is alot of cold air coming in from outsode. The wall we have the Recorder at isnt insulated. Could that be it?
