Be careful about the numbers. Places like Sears and Sams Club get special numbers (like the 5101) and while it looks like the model is newer because of a higher number, it is NOT.
Other than the 5045, I think the 5006 is the latest machine. Mine was made in November 2004 and it has the AllWrite feature. That means it burns video to DVD+ to DVD- and also does VCD and SVCD to CDs. From what I can tell the 5006 is just the 5005 but with the added 3 hr. recording mode.
BTW, I went through four LVW-5006 units and they all had major problems, some in common. See my posts elsewhere. Personally I would not but another LiteOn standalone DVD recorder until I hear they have their very serious engineering problems resolved. I just took the last one back tonight for a refund.
If you do get, or have one, put it in an open area, hook it up, tune it to a cable channel and monitor the output. Look for 'jerky' dropped frame output after a few minutes. Then let it run for several days and see if it is stable. Also do a bunch of test recordings. Assume from day one that it will not work and maybe you will find the needle in a haystack!
Only after a week did mine start really failing with regularity. See my posts elsewhere here with the full details of what is wrong with the LiteOn units. Maybe they will get machines to work by the 6000 series
