Is interlacing compulsory for PAL?

[distendo]

I produce home movies with Pinnacle Studio, until now outputting to AVI for viewing on the PC. They've always been interlaced, and I've used VirtualDub's deinterlacing filter to removed that.
I've now got a DVD burner, and a domestic player's turning up on Friday [I hope]), so there'll be more call to watch them on tv, in PAL format.
I understand from this forum that PAL requires interlaced movies, with field order B.
I believe that TMPGEnc will [at least for 30 days ] allow me to take my AVIs and turn them into interlaced MPEG2s.
Although I'd like confirmations or comments on the above, what I'm wondering is [without wanting to experiment if asking here will sort it much quicker!], what happens if you show a deinterlaced movie on a PAL tv?

Most movies I buy from the UK appear to be deinterlaced and/or progressive format. I'd think the PAL tv would accept the deinterlaced video just fine from a DVD player.

And you can only make MPEG2 wth TMPGENC PLUS. Not sure if they have trial versions of it.

Thank you! [Now I have to look up info on 'progressive format' ]

BTW, I downloaded the freebie version of TMPGEnc, which I believe has a 30-day trial of the MPEG2 codec.

All TVs (except some HDTV formats) require interlaced video (ODD FIELDS, then EVEN FIELDS). Most movies are filmed at 24fps PROGRESSIVE. PAL requires 25fps, which can be accomplished by speeding up film to 25fps, or by adding adding a frame thru a PULLDOWN process (24:1?). When you speed up the film, you also have to speed up the audio. The DVD is most likely stored in PROGRESSIVE format, at either 24 or 25 fps. It has whatever display flags that are needed to display the video properly on your TV.

If your AVIs are recorded at 25fps, then encode as INTERLACED VIDEO (because you can't deinterlace these without jerky video, because the framerate is REAL).
